Very interesting approach of assembling regexes; although this would not generate the results required when inputting real life data like:

my @urls = qw( http://www.youtube.com/user/jantje http://www.youtube.com/user/pieter http://www.youtube.com/user/frida http://youtube.com/user/channel http://youtube.com/channel/doesntexist http://youtube.com/user/blah http://www.youtube.com/user/bianca_sterlings http://www.youtube.com/user/blango );

Which returns:

(?-xism:http:\/\/(?:www\.youtube\.com\/user\/(?:b(?:ianca_sterlings|la +ngo)|jantje|pieter|frida)|youtube\.com\/(?:user\/(?:channel|blah)|cha +nnel\/doesntexist)))

while it should return roughly: ^http:\/\/(?:www\.)youtube\.com\/user\/(.*)$

What this module offers is a rather customized approach of how to create regexes on custom user data, for validation; while I'd like to create a regex on public data to extract the right set of data out of a list of url's. Thanks for letting me know this this one; it's a nice toy to play with :D
