What's wrong with function pointers and delegates? For starters, you 
need to support them for user-written foreach's, and (as long as they 
are written in an alias-free form) they are const-foldable.

What about structs? They are a plain old data type, and they don't have 
virtual functions. Is there something tricky with them that I'm missing?
