Alex Willmer <a...@moreati.org.uk> added the comment:
The re module throws an exception for re.compile(r'[\A\w]'). latest
regex doesn't, but I don't think the pattern is matching correctly.
Shouldn't findall(r'[\A]\w', 'a b c') return ['a'] and
findall(r'[\A\s]\w', 'a b c') return ['a', ' b', ' c'] ?
