I think the problem is that C/C++ interop in practice sucks because they made pointers annoying to use (for ideological reasons. Pointer == Evil).

It's sad because technically they have amazing C/C++ interop, but using s.th. like SDL2 to write some toy game would be way less pain in C++.

You need to link against C libraries as a compiled system language and you just need a lot of pointers to do anything meaningfull in C.
