Say I have two interfaces
interface I { void f(); }
and
interface J { int f(); }
implemented by some class
class A : I, J {
// challenge by the compiler:
// implement f()!
}
VB.NET allows that by renaming the implementation (it does allow
it generally, not only in the corner case).
C# allows that by specifying the target interface when
implementing (can be omitted for exactly one; corner case
handling); the specification makes the implementation private.
(See [1])
Java just disallows the case when two methods are incompatible.
If they are compatible, they must be implemented by the same
method. If they are meant to do different things, you are screwed.
What is D's position on that? The interface spec [2] does not say
anything about that case.
