The whole idea of interfaces is to avoid multiple inheritance.
Hm. I don't believe that. One of the major points of interfaces is indeed to avoid the problems of multiple class inheritance (diamond problems - i.e. problems caused by conflicting implementations of a method in different ancestor classes). But Interfaces themselves don't have an implementation, so those diamond problems simply don't exist for them. I don't think there's a good reason against multiple interface inheritance. Not having multiple interface inheritance complicated certain situations for myself.. forcing me to put runtime interface-casts into my code that a compiler with multiple interface inheritance could have checked at compiletime. -- Andreas _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
