Ermh, I'm afraid I can't follow.  Could you elaborate a bit?

Probably not.  I think I have in mind that the programmer would really
write down a module as 

export interface
+ import interfaces
+ body

Then there'd be a unique, but *separate* mapping of interfaces to
implementations.  I'm not sure this would have to be part of the
language---the linker could figure it out trivially if there's only
one implementation per interface.  This would leave the door open to
later extend things to handle true components.
