Can I just say, as someone who's only been lightly following this 
thread, that the above :(: type stuff

a) looks incredibly ugly
b) gives absolutely no clue as to what it might mean
c) looks incredibly ugly.

There's already prior usage of the : in python for dictionaries, for
slices, but nothing at all like this. I'd really hope we don't end up
with something this awful looking in the stdlib. 

Speaking purely for myself, of course <wink>

(On the other hand, making the operator :( might be a subtle way of
pre-deprecating it)
