So I think this is basically OK, but I have one more request...

Rather than do this, can you just change the elif line to read:
elif ('identifiers' in self.options) or ('functions' in self.options):
...then leave the rest of the code intact? It keeps the logic together,
and avoids the confusing distinction between identifiers=='' and
identifiers==None .
