No, I was after all Perl modules starting with `L' in the sense that I
would say that Text::Abbrev started with `T' rather than `A'.  (I
later replace all `/' in the result of the expansion with `::'.)  So I
did mean L**/*.pm, not **/L*.pm.  However, as Bart rightly guessed,
L{*/**/*,}.pm was a load of rubbish.  I actually meant L*{/**/*,}.pm.
Is there a better way of achieving this?
