Generics ... it depends on how they are implemented.  I'd much prefer functions
that could tell the kind of value they were supposed to return, and selected
the correct function from a full match of the parameters.  So one could, e.g.,
distinguish between:
StringBuffer s = new ("this is a StringBuffer");
    and
String s = new ("this is a String");

Forwarding of dependencies (was that Pizza also?  Or was it Jamie?) would also
be a very nice feature, so that one could have a sort of sideways inheritance.
Very useful in systems that don't permit multiple inheritance.

Then, perhaps, generics.

Speeding things up wouldn't hurt either.
