__missing__ is a dict method. I was merely noting it would make more
sense to override that rather than __setitem__ to avoid slowing down
normal lookups in sys.modules.

However, I'll still advocate the simple approach (two entries) for
now. Assuming uniqueness of values in a dictionary is invalid in
general, so code assuming it for sys.modules is arguably already
incorrect. Definitely a point deserving of more discussion in the PEP,
though.

Cheers,
Nick.
