Local variables shadowed by global variables

[jamesls]

Just started using pudb, and I ran into this issue and couldn't figure out what was going on:

If I have a test script like this:

i = None
def test(l):
    j = -1
    for i in range(len(l)):
        print l[i]
        print l[j]
test(range(10))

And then I:

1. Run the script: python -m pudb.run test.py
2. Set a break point on line 5 (print l[i])
3. Continue until that break point is hit
4. Create an interactive shell with '!'

I get this behavior:

>>> print l
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> print j
-1
>>> print i
None
>>> print l[i]
Traceback (most recent call last):
  File "<console>", line 1, in <module>
TypeError: list indices must be integers, not NoneType

Or in other words the value of i is None, which is the value in the global scope, not the local scope. I would expect this value to be be 0. All the other local variables (j and l) display the values I would expect.

Thanks for the report.
