Let me clarify that I'd be okay with making the keyword optional. It
should probably still be kept around for the occasional use like this:

exec("""def function():
    global {0}
    {0} = 42
""".format('x'))

where the compiler would have little hope of figuring out that the
variable was meant to be global without it.
