This would, if I understand imports correctly, have ham() operate in
one namespace and spam() in another. Depending on what's being done,
that could be quite harmless, or it could be annoying (no sharing
module-level constants, etc).

As to which keyword is used, I would be inclined to go with 'return'
rather than 'break'. The module is thus a procedure in its own right.
Of course, that's assuming the feature's actually needed, which isn't
certain by any means.
