Use frozenset for keywords; allow Pop.

Browse source 
Rather than using tuples for set belonging, use a frozen set. That eliminates the need to separate them by lengths.

Also, 'Pop' is not a reserved word. It's perfectly valid as a possible substitution identifier, so allow it. If used, it will go to the used words anyway and thus will be skipped by the sequential name generator.
