It's not quite the same, because in my scheme the namespace
statement creates a new namespace embedded in the scope
where it appears, whereas Bengt's one seems to just give
a name to the scope itself.

I'm not really in favour of either of these -- I'd be
just as happy with a simple 'outer' statement.
