I added it because we can add a function to a namespace "from outside":

    namespace foo {}
    void foo::bar() { ... }

...but it drags users into the internals of the macros. I am probably going to
remove it, and document that BOOST_OPENMETHOD_OVERRIDE must be in a namespace in
which the method is visible by normal lookup rules.
