Which suggests to me there must be some sort of order of precedence
between __contains__ and __getitem__
and 'for' statement must change the order in some manner.
The 'in' part of for statements has nothing to do with the 'in'
comparison operator. For loops first look for .__iter__ and .__next__
and fall back to .__getitem__.
