At first I thought `hey that's cool!' since I'm kindof sick of typing
has_key() all the time.  But then I realized that this is not really
consistent with sequence types.

    item in list     IMPLIES      list[something] == item

but according to your definition,

    item in dict     IMPLIES      list[item] == something

where in each case `something' is undetermined.  I suggest you rethink
this `feature'.
