in thread using a hash to do substitution?

no_slogan's regex trick is very nice (++), however, I've been led to believe that lots of ors (the | char) in a regex can blow out the stack (or take a long time) because of the back tracking required. Can any more adept monks comment on this?

The other more brute force less pretty way to solve the problem is:

foreach $key (keys %hash) {
    $text =~ s/$key/$hash{$key}/eg;
}
