Yep. Basic hash table. Spec out all undefined behaviour. Standardize abi. Etc. so many things to do with c to actually make it useful instead of c++ lite

> Standardize abi

What's with this strange desire to mandate One True Way to implement function calls in every language implementation? If I want to use rbx/r11/r10/r9 for argument passing and return results in rdx/rsi by default and have to use

     @if os.LINUX and cpu.X64
     import external func[[regseq("rdi,rsi,rdx,rcx|rax"), library("libc.so")]] fwrite(buff ptr, size int64, count int64, stream ptr) int64;
     @endif

to interoperate with one particular implementation of libc for one particular OS on one particular ISA, then that should be perfectly fine.

That in no way conflicts with the existence of a standard. A standard is just a common default, you can deviate from it. And this being C the ability to do so when needed would be expected.

I get why people want those things but you can’t spec out undefined behavior and end up with a version of C that people want.

Not sure what “standardize ABI” is supposed to mean… each platform has its own ABI, and most of those ABIs are already standardized. The standards are just not part of the C standard.
