Nothing here is specific to boost::function. By this same logic, nothing 
should ever be in namespace boost.

You could very well make the case that, indeed, nothing but subnamespaces 
should be in boost. In most circumstances you would be right. But the reason 
everything is in boost is that everything that is accepted into the standard 
would move into std, and putting everything in boost allows us to catch 
problems that would in any case occur when the components are placed in std. 
And in fact, the original problem presents itself with std::function (or 
std::anything else, for that matter) and std::bind as well.
