Today:
• More cleaning (PR).
• Still don't understand compilation of stdlib. I see on the IR->PYAST stage, there are many stdlib files, but it's better to understand what's going on before this stage.
• To do something more handy, found that function references are unsupported at all. Added a couple of lines and +36 box tests pass (PR).
Next time:
• Continuing research of how stdlib files are processed.
• Will also research something else, for example, unsigned numbers. Probably they can be implemented via intrinsics like we do with signed numbers, without touching stdlib.
