One stellar example of this is the countless web pages out there full of HTML and CSS errors which exist thanks to IE's "helpful" HTML correction features and CSS error handling. It may not be the same thing, but I believe it should be as hard as possible to construct faulty regexps. If the regexp is dropped silently it is likely to be far less useful than in the case of the developer being alerted of an error and fixing the error, or in a worst case removing the pattern altogether. .max -- Max Romantschuk http://max.nma.fi/
