You should really be using pychecker (as well as Emacs autocompletion
feature ...):

~$ cat x.py
def foo(x): return x

longVariableName = 1
longVarableName = foo(longVariableName)

~$ pychecker -v x.py
Processing x...

Warnings...

x.py:4: Variable (longVarableName) not used

[I know you will not be satisfied with this, but pychecker is really
useful,
since it catches many other errors that no amount of macroprogramming
would
evere remove].
