However, sometimes you want to ignore more than one argument, in which case this doesn't work:
ryan@DevPC-LX:~$ python3
Python 3.4.1 |Anaconda 2.1.0 (64-bit)| (default, Sep 10 2014, 17:10:18)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> def f(_, _): pass
...
File "<stdin>", line 1
SyntaxError: duplicate argument '_' in function definition
>>>
My idea is to allow duplication of the underscore argument in the presumption that no one in their right (or wrong) mind is going to use it as a real argument, and, if someone does, they need to be slapped on the head.
