Thanks. I think we can proceed with the assumption that it's all
clearly ordered. Even when the scopes are explicit (ie actual separate
block scopes for the variables and no shared scope), doing a 'return'
(or break out of a loop) will obviously exit multiple scopes at once,
so it would be good to have it documented that the cleanup is always
in that reverse order by scope and declaration order within a scope.

I guess I should check with the clang people too.
