C++ passing a value by reference that is created in the function call (inline)

I want to understand why C++20 complains when I try do the following, perhaps someone can help.

I have a method defined, like so:

void doStuff(Point& dest) {
    ...
}

When I try to do the following:

doStuff(Point(x,y));

I get the error: C++ initial value of reference to non-const must be an lvalue

This goes away when I make Point& dest -> const Point& dest or if I define a new variable for the Point(x,y) however in the case that I do not want to defined dest as a const or I dont need a variable, why is it that the compiler complains about this? There are cases where I want to pass it in as a reference and others where I want to keep it inline with the function call to keep things more straight forward. Obviously the example I gave here is really simple, but you get the idea.

Of note I know that I can cast it like so:

doStuff(static_cast<Point&>(Point()));

But this seems really unnecessary, I’d like to find a way to achieve this without all the other nonsense. Any help is most appreciated! I might be missing something really obvious, I am no C++ expert.

>Solution :

you can accept (overload with) rvalue references void doStuff(Point&& dest)

side note: you can pass it directly to lvalue reference version if that’s what you want.

void doStuff(Point& dest);
void doStuff(Point&& dest) { doStuff(dest); }
