[swift-users] It seems like we really need an #include preprocessor directive?

IMHO this seems like a surefire ‘design smell’ — if you have a use case where you find yourself wanting a preprocessor to eliminate lots of redundant lines in your source code, then either your code or the language you’re using have serious problems.

(I see absolutely nothing wrong with inheritance, and it solves exactly this sort of problem. Yes, structs can’t inherit, but they can contain a common struct as a member, which is quite similar and addresses this issue.)
