Base class member implement interface member

[Armin Zingler]

Hi group,

how can I have a base class member implement an interface member?

Example:
class a
sub Member1
end sub
end class

interface I
sub member1
sub member2
end interface

class b
inherits a
implements I

sub member2 implements I.member2
end sub

mybase.member1 implements I.member1 <===
end class

The last (not compilable) line shows what's my intention: The base class
contains the implementation of Member1. As B is derived from A, it should be
possible to have (the inherited) Sub Member1 implement I.Member1 because
Member1 is also a part of class B. Isn't it possible?

Currently I have to write the implementation in B and delegate the call to
MyBase:

sub I_member1 implements I.Member1
mybase.member1
end sub

The more members, the more work... And it gets (a little) slower due to
delegation.
