[Boost-users] [result_of]

13 Oct 2009

      Hi All,

I've noticed that if do,

class A: F{
    template<typename S>
    struct result{};

    template<typename A1,typename X>
    struct result<A1(X)>{
      typedef ... type;
    };

};

result_of<A(X)>::type

tries to deduce the result type from F (not accessible because private), 
so I'm left with having to keep F in a variable:

class A{
    // ...

    private:
    F f;
};

Any suggestion for keeping F as a private base?
