It seems a reasonable thing to suggest. Instead of
a copy, locals() could return a mapping object that
is a view of the underlying array. The only limitation
then would be that you couldn't add new keys.

That's because the topmost frame has a module's dict
as its locals, so in that case you are modifying them
directly. It's only code compiled as the body of a
function that uses an array for locals.
