Description

Can't use 'template' keyword to specify the function is template when the function is operator().

Below code should be compiled, but compiler complains of a line around (d) while it compiles (b) without any error. (Other major compilers like gcc/clang accept (d), but rejects (c))

The code should be compiled to increases portability of msvc based code, since the some other major compilers only accept (b) and (d).

struct s
{
    template<typename>
    void a() {}

    template<typename>
    void operator()() {}
};

template<typename T>
void t()
{
    T a;
    //a.a<int>(); // (a) should be compile error, but VC allows it now.
    a.template a<int>(); // (b) should be compiled, and VC allows it now.
    //a.operator()<int>(); // (c) should be compile error, but VC allows it now.
    a.template operator()<int>(); // (d) should be compiled, but VC doesn't allow it.
}

int main()
{
    t<s>();
}
