For which reason I propose that Python 3.0 have the control name in any for expression be "local" to the expression ;)

Hmm - actually this does raise another issue.

    >>> x = 1
    >>> y = [1, 2, 3]
    >>> y = [x for x in y]

Using the current semantics:

    >>> print x
    3

Using the new semantics:

    >>> print x
    1

Is this a problem? Are the new semantics going to cause confusion?
