Well, it does have:
>>>? [x==3 for x in [1,2,3,4,5]]
[False, False, True, False, False]
This is IMHO much more intuitive than your construct overloading "==".
It is also more flexible (any operation can be performed on x, not just
an equality comparison).
So sorry, but I can see no justification for changing the Python
language to do something, which can already be done, to be done in a
more obscure way.
is already legal syntax (it evaluates to False, since the operands are
not equal), so you are proposing a code-breaking change.
Apologies if someone has already pointed all this out, as is very likely
