That's only because of #include, however. preprocessing is very fast, it's just because C++ lacks a sane way to import definitions that it dumps a huge amount of text into the frontend of the compiler.
How do modules work with generics and cross-module inline functions? Probably I can find the answer in D or Rust but I am not familiar with their mechanisms. Thanks.
In Rust, the library format also includes a pre-compiled version of the generics needed, and so when the compiler includes the library, it can monomorphize from there.
