New submission from Brandon Corfman: Python's documentation for the re.match function is match(pattern, string, [flags]) where pattern can be either a regex string or a compiled regex object. If it's a compiled regex object, then supplying an optional flag to re.match (in my case, re.IGNORECASE) doesn't work and, more to the point, fails silently. I think this should throw an exception if it's not going to work.
See http://mysite.verizon.net/bcorfman/2007/12/something-i-hate-about-pythons-re.html for a discussion.
