Can you show us a code snippet? What are you trying to do the substitution on? The following works, but I think it's not what you are asking for.

#!/usr/bin/perl -w
use strict;

my %hash = (
  foo => 'bar',
  baz => 'quux'
);

my $string = 'foo and baz';
while( my($k,$v) = each %hash ) {
  $string =~ s/$k/$v/g;
}
print $string;

What I'm asking is: "what is your substitution target"? Are you trying to simply make substitutions in a string, like I did above, or are you trying to munge hash keys or something strange like that?
