Description Tommi 2013-06-20 14:02:16 UTC 
Assignment operators should return by ref, not by value.

void edit(ref int) { }

void main()
{
    int n;
    edit(n += 4); // OK
    edit(n = 4); // [1]
}

---
1) Error: function main.edit (ref int _param_0) is not callable using argument types (int)

This code compiles succesfully today. Closing as w4m.
