Question

I would like to make an alias in C++ to singleton calling
so instead of calling MYCLASS::GetInstance()->someFunction(); each time, I could call just someFunctionAlias(); in my code.

Answer 1

Use a static function.

namespace ... {
    void someFunction() {
        MYCLASS::GetInstance()->someFunction();
    }
};

Edit: Sorry lads, I wrote static someFunction and meant void someFunction.
