 {{{
         // - swap_impl has a using-directive, rather than a using-
 declaration,
         // because some compilers (including MSVC 7.1, Borland 5.9.3, and
         // Intel 8.1) don't do argument-dependent lookup when it has a
         // using-declaration instead.
 }}}

 IIUC, this isn't because of a peculiarity of any compiler: the standard
 says that ADL operates on names brought in to associated namespaces
 through using-declarations, but not on those visible by using-directives.
 A using-declaration is a declaration, while a using-directive is not :-)
