| from the jeffrey friedl report: The way (?i) works now is that if it appears anywhere in the regex, it turns on case-insensative matching for the entire regex. This is different (and less useful) than how Perl or Sun's Java package does it [I'm pretty sure SRE does it this way to exactly match the version of PCRE used in 1.5.2, but maybe it's time to move forward... /F] | ||

| This is still a valid issue. (As of Python 2.6a1+ (trunk:61434, Mar 17 2008, 08:06:54).) >>> bool(re.match("abc(?i)","AbC")) True The documentation says that the behavior of a regex with (?) not at the beginning is undefined. Short of implementing Java/Perl behavior, this should be made an error rather than undefined so that users porting their code from Java/Perl get an early warning. | ||

| I don't think this should be changed anymore, at least not without a flag. Anyway, it is implemented in #2636. | ||
