Question

Operator= in C++ inside a class is being declared like this:

 MyType & operator=(const MyType & rhs);

It is reasoned like it is necessary for chaining. But, as operator= has right precedence, then returning the value should be enough.

Answer 1

You certainly can declare operator = with a non-reference return type. In fact, on the very rare occasions I implement it, I normally make it return void as I don’t think that multiple assignments, or testing the result of assignment, are one of C++’s greatest features.
