A long time ago (probably last millennium) someone (probably Chip)
discussed the possibility of nicking the zsh globbing code and using
that, along with the extended globbing syntax.

Not sure how feasible that is, but I do wish it were possible every time
I write something horrible like:

  my @files = split " ", `zsh -c 'echo **/*.pm'`;
