All name binding operations have both compile time and runtime
semantics, so that's OK. 'nonlocal' and 'global' are actually the odd
ones out since they *only* affect compile time and don't actually
correspond directly to anything in the generated bytecode (instead
influencing the way the names they specify get treated in other parts
of the code).

If a "function state decorator" approach is used, then yeah, I agree
it should come immediately before the main part of the function
header. However, I'm not seeing a lot to recommend that kind of syntax
over the post-arguments '[]' approach.

Regards,
Nick.
