1015. Template arguments and argument-dependent lookup

Section: 6.5.4  [basic.lookup.argdep]     Status: C++11     Submitter: Jason Merrill     Date: 2009-12-24

[Voted into the WP at the March, 2011 meeting as part of paper N3262.]

Currently, according to 6.5.4 [basic.lookup.argdep] paragraph 2, explicit template arguments in a function argument do not contribute to the associated namespaces in a function call, although they plausibly should in an example like the following:

    namespace N {
        struct S { };
        void f(void (*)(S));
    };

    template<typename T> void g(T);

    void h() {
        f(g<N::S>);    // Should find N::f
    }
