RE: Unknown level of hash

I meant more that my answer was more "fun" than "useful."  I can't
imagine a reason one wouldn't prefer a loop to an eval.  :-)

Well... that's not exactly it, but you can implicitly hijack the loop
behavior of things like map and grep, using them in void contexts.  I
think another poster showed a clever way to do that with a map.

The dim solution for perl6 was really interesting though.
