struct QString
{
ref QString opOpAssign(string op : "+")(ref QString s)
{
return this;
}
}
void main()
{
QString s;
s += s; // fails
s.opOpAssign!("+")(s); // compiles
}
test.d(12): Error: variable test.QString.op only parameters or foreach declarations can be ref
Compiles if the return type is omitted or the operator is called explicitly.
