[Python-Dev] ACCEPTED: PEP 285

[Gustavo Niemeyer]

Hi Neal!

> 	    if a is True: print 'True'
[...]
> 	test.py:6: Comparisions with True are not necessary

Testing if "a is True" is ok. True and False are singletons
this is the best way to know if 'a' is really 'True' (and not 1,
[0], "foo", etc). This test will be necessary sometimes.

> 	    if a == False: print 'False'
[...]
> 	test.py:7: Comparisions with False are not necessary

This should probably say something more agressive, like
"Comparisions with boolean values may be dangerous", since this
may give undesirable results (if the user was trying to check
for False, and not for 0, [], "", etc).
