Newbie to Perl, but just found myself in similar circumstances. For what it's worth, I'm using a two dimensional array with map, i.e.,

my @SUB_REC = map {[qr{$_->[0]}, $_->[1]]} (
  ['(robert|bobby)', 'bob']
);

[download]

where the first element of each row is the regex and the second element is the substitution. Then simply use

foreach (@SUB_REC) {
  $yourText =~ s/$_->[0]/$_->[1]/g;
}

[download]

Obviously you can add more elements to the array for flags.
