Since in this type of situation I'd normally expect the one pattern to be matched against many strings, I'd usually aim to approach this instead by modifying the regexp:

my @ignore=(' ','-'); #whatever my $ignoreclass = sprintf '[%s]', join '', map quotemeta, @ignore; $re = join $ignoreclass, split //, $re;

Of course this is only so simple if the initial pattern is a simple string: a full-on regexp is rather more difficult to introduce such modifications to reliably.
