I think it would be trivial to write a subroutine in perl that takes a string and splits it on '^', '$', '.*' and then recombines the string as a regex, with the rest of the string regex escaped.

The above would allow for user to specify a regex and be secure for untrusted users. This can also be expanded to include many more features.
