Increase typing coverage

[Samoed]

Make library fully typechexked. Integrate mypy typcheking for this. Not sure how much it is correct, because there is no tests. Maybe would be better to create tests firstly

Let's avoid this dependency

[Samoed]

Ucall is used a lot inside library. Is it expected to be an optional dependency?

Our lines are 120 lines wide - surprised that this is warping 🤔

When I tried to build this on mac I got error

      error: invalid argument '-std=c++17' not allowed with 'C'
      error: command '/usr/bin/cc' failed with exit code 1

and I fixed it with

from setuptools.command.build_ext import build_ext as _build_ext

# Flags that are only valid for C++ compilation
cpp_only_flags = {"-std=c++17", "/std:c++17"}


class MixedBuildExt(_build_ext):
    """Build extension that applies C++-only flags only to C++ source files."""

    def build_extension(self, ext):
        original_compile = self.compiler.compile

        def patched_compile(sources, **kwargs):
            c_sources = [s for s in sources if not s.endswith((".cpp", ".cxx", ".cc"))]
            cpp_sources = [s for s in sources if s.endswith((".cpp", ".cxx", ".cc"))]
            objects = []
            extra_args = kwargs.get("extra_postargs", [])
            if c_sources:
                c_kwargs = dict(kwargs)
                c_kwargs["extra_postargs"] = [f for f in extra_args if f not in cpp_only_flags]
                objects += original_compile(c_sources, **c_kwargs)
            if cpp_sources:
                objects += original_compile(cpp_sources, **kwargs)
            return objects

        self.compiler.compile = patched_compile
        try:
            _build_ext.build_extension(self, ext)
        finally:
            self.compiler.compile = original_compile

setup(
    ...,
    cmdclass={"build_ext": MixedBuildExt},
)

Not sure if it is good (I asked to fix claude), but I thought you might be interested
