Suggestion: Python global scope

I've been tossing this idea in my mind for some time now:
In Python, declaring a variable using the global statement automatically
makes it available in all subsequent scopes.
But to me, it makes more sense to use the global statement to 'import' a
variable from the global scope into the current scope. For instance:
X = 1
X = 2
Currently, this will print 1, 2, 2 and 2. But if global would be limited
to current scope, it would print 1, 2, 1, 1.
'X = 2' would work on the local version of X, 'global X' will 'import'
the global X into the local scope, so any actions on X would reference
the global X, rather than previous X.
