Began work on Diyrbal's grammar.

I've started it bottom-up before, started from the VM, then the GC, then the JIT, etc. I've given up on several iterations because of this. I think I've implement Mark&Compact GC about 4 times now.

If i write the grammar first, I can have a much more clear path going forward.

And yes, it's Wirthian. So what.
