Hi All,
 Request your help on hot to create a pointer for a function 
whose function type is Result.

```
ReturnType!(typeof(&test)).stringof; // Result

To get a function pointer type from a function type, you can add 
`*` on the end:

    void func(int) {}

    alias FuncType = typeof(func);
    pragma(msg, FuncType); // void(int)

    alias FuncPtrType = FuncType*;
    pragma(msg, FuncPtrType); // void function(int)
    static assert(is(FuncPtrType == typeof(&func)));
