This crashes the compiler for me (winxp).
If i change "interface" to "abstract class" (1) it works, but no 
multiple inheritance.
If I change "void" to "abstract void" (6), i get:
collectionstmp.d: class Abstract interface function Interface.foo is not 
implemented
If i remove the templating and replace T with Object everywhere, I get 
the error
collectionstmp.d: class Abstract interface function Interface.foo is not 
implemented

Do abstract classes actually work?
