I don't see where shadow functions are really necessary -
after all, no one has ever complained that you can't do
pp_chomp(sv); /* or pp_add(sv1, sv2), for that matter */
in Perl 5. Quite frankly the shadow thing sounds like a
bundle of unnecessary function calls.
But that's just my opinion, feel free to disagree.
