Yes, I am. I realise that there is far too much history in both Computer
Science in general and Python in particular for it to ever happen, but I
do think that that is how it should be in the ideal language. The
concept of True or False is distinct from the concept of a number, and
I'd like to see it stay that way in the language.

Yes, you would be writing a lot of 

if bool(expression):

rather than

if expression:

But I think it would be much more clear and less awkward.
