Issue 25964: optparse.py:1668: (file) shadows builtin

I use pychecker for checking my python code. Seems optparse.py distributed with python-2.7 could be improved as well:

[system path]/optparse.py:1191: Function (__init__) has too many arguments (11)
[system path]/optparse.py:1206: Local variable (version) shadows global defined on line 10 in file my-test-code.py
[system path]/optparse.py:1400: Local variable (stop) not used
[system path]/optparse.py:1668: (file) shadows builtin


Interestingly, my version variable is overridden by one from optparse.py. But more worrisome is the 'file' variable name.

None of this warnings highlights a real issue. Furthermore, optparse module is deprecated and you'd be better off using argparse instead.

But couldn't somebody just rename the variable for example to _file? I see optparse also in python-3.5 so I did not think it could be Deprecated.

The deprecation warning is clearly displayed at the top of the module documentation: https://docs.python.org/3/library/optparse.html 

Regarding variable names: it is not an issue and pychecker is simply mistaken here.
