Public bug reported:

It would be nice if pyflakes could detect mistakes like this:

       try:
           oldtime = os.path.getmtime(fname)
       except OSError, IOError:
           oldtime = 0

In the general case, it's obviously difficult to tell whether this is an
error or not; but I suspect that handling the exception variable name as
a binding would give you a "redefinition of Foo" warning in most of the
cases where a mistake has been made.
