I thought of another question while reading these responses. If I want to read in the substitution value from a file and the substitution contains backreferences, how can I make that work? For example: 
my $new_value='$2 and $1';
my $string="(Jack) and (John)";
my $regex=qr/$string/;
$string=~s/$regex/$new_value/;

This obviously won't work how I intend, but how would I do this?
