>Is this even possible, theoretically speaking? i wondered that myself. I think it's correct to say that a regex can't match an unbounded number of characters unless it contains one of the quantifiers indicated. So the question is whether these quantifiers can be detected reliably using a regular expression applied to the regular expression. It's certainly tricky to distinguish true quantifiers from strings that look like quantifiers but are escaped with backslashes or square brackets, but I suspect it is possible. But like others I also wonder whether correctly recognizing such regexes actually achieves the underlying intended (but unstated) purpose. Michael Kay Saxonica
