Wow! Im impressed, where were you when I wrote the first node? :-) Very nice idea indeed.

But, unfortunately it doesnt address the question im trying to solve. My question is this: given an arbitrary blessed scalar ref, how does one efficiently determine if the object is in fact a regex? Your solution, which i personally think is rather ingenious, solves "How do I make a blessed ref, when stringified, return the pattern?". Which is I think useful indeed, but unfortunately not what I need. (I recognize I may not have specified the requirement sufficiently.)

Even though this is a solution from the point of view of designing a class, it has the problem that its underlying concept, that of qr//ing the value, doesn't generalize. How do you detect a failure? There would be no way to determine if the wrapped object actually had produced regex, or just a ref stringified, or any number of other magic events.

Anyway, ++ for the idea...
