[Andrew Kuchling] > Oh, and another possible 2.3 thing: is it time to drop the PCRE code? Whatever /F says. Over and over we've gotten reports that some naively written regexps that work OK (albeit slowly) under pre "blow the stack" under sre. The suggested workaround has been to "import pre as re". So we break working code if the pre engine goes away before /F thinks sre is as forgiving in these nasty cases.
