On: CXX – safe interop between Rust and C++

[lifthrasiir]

It seems that the C reimplementation is becoming a preferred approach for C FFI in recent languages---at least ones that can afford the cost. Not just D's ImportC but there are other examples like Python cffi. C++ FFI is another story though.

Zig has C++ FFI

[lifthrasiir → melony]

Zig's C and C++ FFI is basically based on embedding clang, which seems the only way for its level of FFI in case of C++. For C it is much more doable to make a new C compiler specifically for FFI.

D's ImportC also allows the C code to be extended with D-ish features, like forward references, compile time function execution, and modules.
