Thread 106303483

Is it true guys? Is C++ finally going to get reflection? Are you guys excited for it just as much as these C++ experts?

>being excited for any developments in the exploit riddled, memory unsafe language
Rust won btw

Gee I can't wait to use this in 2035 when compilers finally implement it

>>106303546
2055 for industry to adopt it...

What C++ needs is to include functionality for parsing and analyzing C++ code in the standard library.
Then you can just write a metaprogram that operates on your source code and generates the code you want.

I think this is a trap like lots of other C++ features. I tried reflection in Rust, and it always overcomplicated shit compared to just using a mutable object type and serializing/deserializing it to/from a regular non reflected struct.

ready for 3 times the size of the executable.

>>106303483 (OP)
I bet its crippled and almost useless. Which is pretty much the standard for every new c++ feature. They make sure to take what could be a game changing feature, and reduce it down to the absolute minimal amount of functionality. Ensuring massive additional complexity for minimal utility.

>>106303483 (OP)
You could already do this on nearly every modern platform by dlopening yourself.

It's almost always useless.

It's crazy how every C++ feature sounds so exciting and then has half a dozen exceptions that make it completely useless in practice. You might as well just use C.

Think how amazing C++ will be when you're long dead.

>>106305107
Backwards compatibility, baby.

Usecase?

Version pinning:

what is reflection? eili5

>>106307630
The code examining itself.

>>106307630
Autogenerated type metadata

<--- yeah, Rust won
