Support for matching on a Regex

[youngm]

What is your idea?

It would be nice if I could match on a regex and not just a wildcard sometimes

Would you be willing to make the change?

Maybe, but probably not. I can see in the wildcard PR a log of thought went into that as a potential precursor to regex. I wouldn't expect I could take all that forethought into account by implementing it myself.

Additional context

We also have a need for wildcard match ignore case (a separate ticket) which could also be handled by a regex rule.
