In my opinion, interfaces should not need to be implemented in an abstract class. They should simply be inherited as an abstract method. As it stands, you need to explicitly define the interface method in the abstract class (even if you only define the method as abstract).

Interface Foo
	Method SomeMethod:Void()
End

Class Bar Implements Foo Abstract
End

Class Test Extends Bar
	Method SomeMethod:Void()
		' method contents
	End
End

Function Main:Int()
	Local bar:Bar = New Test
	bar.SomeMethod() ' Error : Identifier 'SomeMethod' not found.
	Return 0
End

Hi,

I quite like this idea, but unfortunately it looks like C# might not (see 2nd last post):

Will have a look into it though.

Surely you could make trans silently add them?

I knew that was coming...

Hi,

Yes, but it's gone from being a 5 minute job to a semi-major one!

Anyway, moving this to programming for now...will think about it.
