My gut knee-jerk reaction is to command "don't do that" while simultaneously inquiring "Is that the Perl 4 way of making a closure?" What the heck is that?!? =]

If you are trying to make a closure, there are cleaner ways of doing so. Just do a search here for closure and you will find lots of examples. I also suspect that if you did not receive a response for your perlbug, there is a good chance that either it was not understood or there is a better way to do what you want.
