Oh I'm sorry. Of course the specs always win ... DON'T APPLY THE PATCH !

What do the specs say about the namespace the inserters should be
in or not ? My compiler doesn't find them when I try to use them
implicitly inside the namespace I think they belong, i.e. the module
the structures/interfaces are defined in. I simply can't imagine that
they have to be in the global namespace ?!
