Somewhere else in this byzantine thread, I realised that what was really
bothering me was the conditional semantics that dict ended up with (i.e., it's
behaviour changed significantly if the default factory was set).
If we go back to your idea of collection.defaultdict (or Alex's name
collection.autodict), then the change in semantics bothers me a lot less, and
I'd be all in favour of the more usual variant (where "key in d" implies "key
in d.keys()".
Cheers,
Nick.
