I expected that in this case opAssign is called, not the postblit, beause I
return by ref and assign then the ref to a new value.

But if you change A to this:

[code]
struct A {
public:
    int id;

    this(int id) {
        writeln("CTor ", id);

        this.id = id;
    }

    this(this) {
        writeln("Postblit ", this.id);

        this.id *= 2;
    }

    void opAssign(ref const A a) {
        writeln("opAssign L: ", a.id);
        this.id = a.id;
    }

    void opAssign(const A a) {
        writeln("opAssign R ", a.id);
        memcpy(&this, &a, A.sizeof);
    }

    ~this() {
        writeln("DTor ", this.id);
    }
}
[/code]

You see still the same output, no call of opAssign by 'getA':

----
CTor 42
opAssign R 42
DTor 42
Return A
Postblit 42
DTor 84
DTor 42
----

Or did I miss something important here?
