no, it's not. the return type will be taken from the first
return
statement in code.
auto foo() {
if (1) return 1;
return 2.0;
}
This returns double. Try for yourself.
That doesn't help at all. I want return by ref when possible,
not always return by value. If I wanted return by value, I'd
just return by value!!
you can't return ref and non-ref simultaneously from one
function.
Of course, what I want is:
1. If both returns are lvalues, return by ref.
2. Otherwise, return by rvalue (regardless if one is an lvalue).
