Yuk. Is it ever desirable for an argument of type boost::function to
cause lookup in namespace boost? Probably not, right? That would argue
for moving boost::function into an ADL-blocker namespace.

And perhaps boost::bind and its placeholders should also be in an
ADL-blocker namespace, but I seem to recall that the placeholders are
not in any namespace for legacy reasons, is that right?
