Even the new language features are botched in several ways compared to other languages. It's like the community is full of masochists.

The automatic npc answer is:
>MUH BACKWARD COMPATIBILITY! REEEE!
Imo it's just a weak excuse for retarded choices. The whole language is a big tragedy of the commons and lack of comprehensive planning.

severe case of retardation

There are less Rust threads nowadays, and more and more complaining about C++. They're giving up and accepting their fate.

Why do these ragebait threads never name a single specific thing? Who does nobody ever call out OP on this? It's like the entire thread is bots.

Header hell forexample .... forward declarations are just as painful and dumb like 30 years ago. Every strategy to minimize complexity has some major flaw because the language is designed in such a stupid way.
They created modules now what is just as bloated and painful as header fuckery but in a different way.
These things are much simpler in other languages. The C++ committee lives in a bubble.

Not a C++ feature.

By keeping the constrains outside of code and moving them in to comments or documentation(if you even do that), you are only archiving an illusion of simplicity. By avoiding formalization, you are skipping the short-term chore with a permanent cognitive overhead, which at some point in future will overwhelm you and you will inevitably start making mistakes.

>>105736471
Comments never overwhelmed me because I don't waste my time writing them.
Code is self explanatory, to me. I am the only person who matters, nobody else asked me anything about my code, so 0 people would benefit from comments.

>>105736263
skill issue

>>105736814
>Comments never overwhelmed
I am not talking about comments per se, but complexity. The complexity is unavoidable and it has to be dealt with. Both writing comments or brute memorization can be used, but given large enough scope, both will fall short to formalization.
>Code is self explanatory
It only is until it isn't. We use names, types, signatures, templates, abstractions, etc to express these invariant in the code itself so it can better explain itself and how to properly use it.

I think header files are good for compiled languages. Module based languages seem less able to glue together random bits of code.

In regards to forward declaration. I am currently working on my own fork of c++. One change I want to make is to significantly loosen the forward declaration requirements. Specifically, I will delay parsing of function bodies. This will allow declaring functions within a translation unit in any order.

>>105737197

how???
its just the explanation for the rest of your program what goes where and how we do things

>>105734954
Explain std::move. I'll wait.

>>105737243
the easiest way to understand is you change the scope of a stack variable. say i have a pointer that contains stack variables. you can move a local variable to that pointers memory location, so it doesnt fall out of scope and u dont have to allocate heap memory. also when you compile functions under the hood it does an std::move for any variable you return. this prevents unnecessary copies.

>>105737243
static cast to &&, which tells compiler to use the && overloads of functions

>>105737243
i did a bad job explaining possibly if u have no idea what i am saying. here is a clear example.
#include <iostream>
#include <vector>

class C {
public:
std::vector<int> mem;
C() { };
~C() { };
};

void do_move(C& c)
{
std::vector<int> local = {1, 2, 3, 4};
std::cout << local.data() << "\n";
c.mem = std::move(local);
}

int main()
{
C c;
do_move(c);
std::cout << c.mem.data() << "\n";
}


without the std::move it will do a copy of the data.

>>105737315
>>105737365
wrong. std::move is just a hint to compiler to attempt to turn the l-value into r-value. If the object supports copy, compiler might choose to do a copy instead of moe.

Next question:

what is the difference between:

SomeClass(SomeType&& bla) : bla(std::move(bla)) {}

and

SomeClass(SomeType&& bla) : bla(bla) {}

Does the std::move in this example matters?

>>105737442
you're clueless

>>105737466
See. As soon as I start asking more intricate questions, your understanding crumbles. Sit down and listen: as soon as you assign r-value to a variable, it becomes an l-value. Doesn't matter that the type says &&. Therefore, the std::movie is necessary in the example above to for a move to actually be performed.

>>105737214
They suck. What other language do you have to edit a function signature in 2 places? It's the one thing that Rust does better than C.

Cringe, or based. Call it.

All these words when you could have just looked at how std::move is implemented to see you are wrong.

What do you think std::hardware_destructive_interference_size does?

This is just them being unable to pick a reasonable name for something.

>>105733647 (OP)
Because its a piece of shit from the stone age with mountains of shit slapped onto it

>>105736814
Yeah. Code should be readable without comments. The comment should be in the value/function/type names.

This but ironically.

std::launder is a compiler hint, move has actual semantic meaning

>>105739159
I have been working on a few other features too.

Allow the declaration of private class methods without forward declaration in the class body. This means you don't have to shit up the public interface with private methods.

Another feature which I am very proud of. Is a custom attribute for arrays. Which allows the array to be initialized with initializers of heterogeneous types. Typically used with byte arrays, this feature extracts the byte representation of any expression in the intializer list. Very useful for creating a constant byte array comprised of different struct types.

Another ancillary feature I am adding related to the a fore mentioned heterogeneous array initializer feature. Is the ability to assign names to array elements. This feature will be usable with __builint_offsetof such that you can build complex file formats at compile and have header fields in one part of the generated file format refer to the offset of other parts of the file.

Its easy when you only have 3 headers in your school project.
Try to manage a project with millions of lines of code and get it compiled under 10 minutes.

>>105740064
It's really not that hard to use header files effectively. Stop including so many other headers in your headers. You can even avoid most forward declarations by giving your objects a private object.

>>105739287
move is just a cast to && and has no semantic meaning, nothing is moved, RVO is the only case where the object is *gasp* moved out from a function back into the callee's chosen memory. C++ is a joke.

This. Bjarne has been going off on the committee lately for destroying his life's work.

>>105740918
It's not a cast to &&, it's a cast to rvalue and then an rvalue can bind to a && (an rvalue reference).
&& is a value type, rvalue is a value category
