Note: This enhancement request (in my opinion) is related with the compiler
frontend (of C++ and probably also C) and can be applied to all platforms.
Given a .cpp file (3 lines below only, nothing else);
int main()

It's not perfect, but for this case std::result_of works if you get the syntax
right :

With a small testcase it works:
struct Y {};
struct X {
Y y;
float real;
float imag;
};
struct X __attribute__((noinline))
foo (float *p)
{
struct X x;
x.real = p[0];
x.imag = p[1];
return x;
}

I guess I'm going to reduce the big one with 'delta', if you have special
