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. -- BKS __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!
