I am trying to create a sub that will take a filename (e.g. page-gen.pl) and make it fit in a regex. Backslashing characters is easy, but I can't find a way to get rid of the natural caps-sensativity of regex. What I have so far should show the method I am trying: 
sub Regch{
    $_[0]=~s/(\.|\-|\(|\)|\[|\]|\{|\}|\?|\/|\\|\^|\*)/\\$1/g;
    $_[0]=~s/([a-zA-Z])/[$1]/g;
    return $_[0];
}

It would be nice to have suggestions on how to do this or any PERL modules that would do better. Thanks.
