in fact, your code shouldn't be some thing like 

    my $pattern = qr{ab[crdnfqm]def};
        if $string =~ m{ ($pattern) };
                 ....

which doesn't find all strings with the pattern.

I don't understand trailing xms at the end of pattern.

I think you should forget my previous solution as the user should type all the qr which is not convenient
