It's probably a misfeature of the global statement that it allows
that, but if we're going to re-use it in the form of a "global x in
scope" statement, we should keep the behaviour the same for nested
scopes in the interests of consistency.

Maybe this is an argument for introducing an "outer" statement,
which requires an existing binding (determined by existence of
an assignment at compile time) even for the module scope, and
deprecating "global" altogether.
