Which is strong evidence of a bug in your code. You're trying to tell me that you want a way to enforce that, if the regex doesn't match, it's a bug in your code. This seems to do that perfectly well. If it's NOT a bug when the regex doesn't match, you have the standard conditional form available. I'm not seeing a problem here.
