A first class object is one that can be passed to a procedure as an argument,
and returned as a value by procdedures. I dont have the references, but it
is in common use (especially among Schemers). I dont wish to speak for Patrick,
but "function" has (at least) two different meanings: the definition you gave,
and the definition mathematicians use.
