You seem to be talking about run-time compilation of new subroutines. While that can be a powerful technique, it is different than closures (to me, at least).
Yes... casually, people say "closures" when they mean "anonymous subroutines". But properly speaking, a subroutine (anonymous or not) is not a closure unless it also captures lexical state that can go out of scope. See Closures (was Re: for loops) for an example of detection.
