Summary: Unexpected feature vs. integer and True values

Initial Comment:
Integer 1 interpreted as True.
I didn't expect the following:

Python 2.5 (r25:51908, Apr  4 2007, 10:19:35)
[GCC 4.1.1 20060724 (prerelease) (4.1.1-3mdk)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

>>> v = 2
>>> 0.0 if v == True else float(v)
2.0
>>> v = 1
>>> 0.0 if v == True else float(v)
0.0

I know how to fix this, by writing

0.0 if v is True else float(v)

but to casual observer it is not obvious...

It may be, but it is not a bug (bool inherits from int) and documented (I
think...).
