It isn't ignored, but it shouldn't make a difference since normally at
module level locals and globals are the same. It makes a difference in
an exec() that uses separate locals and globals dicts. For example:

    >>> exec('print(x)', {'x':'G'}, {'x':'L'})
    L
    >>> exec('global x; print(x)', {'x':'G'}, {'x':'L'})
    G
