I wasn't thinking of the user to drop things into boost, this is
obvbiously not supported. I was thinking of this:

namespace foo {
  namespace boost { // <-- Is this "allowed" by boost?
    template< typename T >
    void checked_delete( T* );
  }

  class A {};
}

foo::A* bar = new foo::A();
::boost::checked_deleter< A >()( bar );
