[New-bugs-announce] [issue6119] Confusing DeprecationWarning

[Alejandro]

New submission from Alejandro <alejolp at alejolp.com>:

Comparing a lambda and a built-in by equality ("==") raises a
DeprecationWarning when the "-3" flag is used on Python 2.6.2:

$ python2.6 -3
Python 2.6.2 (r262:71600, Apr 28 2009, 16:17:29) 
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> (lambda x: x) == eval
__main__:1: DeprecationWarning: builtin_function_or_method inequality
comparisons not supported in 3.x
False

On Python 3.0.1 it works just fine:

$ python3.0
Python 3.0.1 (r301:69556, Apr 28 2009, 19:47:09) 
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> (lambda x: x) == eval
False
>>>
