That's nice, but it doesn't deal with the real novice's usage, which is
to learn at the >>> prompt, not in modules.
E:\tmp>cat > foo.py
cat: Reading input from keyboard:
a = 3
ActivePython 2.2.0 Build 221 (ActiveState Corp.) based on
Python 2.2 (#28, Mar 28 2002, 12:10:20) [MSC 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from pychecker import checker
>>> import foo
foo.py:2: Local variable (a) not used
that's nice, but:
>>> def foo():
... a = 3
... return 3
The fact that it doesn't pick up on the unused variable is too bad. The
integration I'm thinking of would be deeper.
