This sounds to me even messier than the C header file mishap,
or even the old K&R days without protoyped declarations!

How can the programmer know about the signature of a method?
I guess from some documentation. And the prime documentation of
an interface is a formal interface definition provided by the
language. This is e.g. what Ada does. Also CORBA is build around
its IDL (Interface Definition Language) and from version 3.0
onwards a CDL (Component Definition Language).

If I understand you correctly the use statement is more like a
linker/loader directive than a compile time interface include?
BTW, is it foreseen to have a clear conceptual split between the
compiler and the loader? Or is that all blurred?
