Re: Question about interface

Actually I would just implement an abstract method, Travel(), and let *its*
implementations in child classes decide whether to fly or swim.

Multiple inheritance is one of those sexy ideas that degenerates into a
quagmire of spaghetti very quickly. Interfaces let you implement a species
of mixins which is IMO about all MI is good for anyway.

If you really want MI, however, the Eiffel.NET language *does* provide it.
It even provides generics without waiting for CLR 2.0.
