Yes, this goal is loaded with engineering/design tradeoffs that we will have to carefully balance.

Swift currently has pretty great interop with C and ObjC through the ClangImporter.  Extending that to C++ is natural once we have time to tackle it and do it right.

I see no reason that we couldn’t have importers for other languages implemented in the same way.  For example, it would be very interesting for swift to be able to import a Java or C# package and just call methods directly on their objects, just like we do for ObjC.
