Block that should never execute except in strange edge case scenarios

Since `re` is a standard library module this import should succeed in any standards compliant python installation that hasn't had some form of `sys.path` manipulation that introduces a module `re` earlier than the standard library module. If checking this behavior is actually intended then it really deserves some form of documentation as it is entirely non-obvious that you have to check for an import failure here. If it is just an import error check then you should catch just that exception instead of catching all exceptions.

Perhaps the logic here can be expressed some other way that doesn't open up as many possibilities for bugs?
