Document return-type polymorphism in FFI #508

Closed ergl closed 2 years ago

ergl commented 2 years ago

This documents the new feature to be introduced in https://github.com/ponylang/ponyc/pull/4060, so this shouldn't be merged until that becomes available in a release.

@redvers Let me know if this new section would have helped you with your issues. It doesn't cover generics since the interplay between that and FFI is a bit complicated from the type checking perspective.
