check what `op` is. pretty sure it is "+" not "+=" so your
element isnt' saved anywhere. also a bit iffy there isn't a
member here to work on
Yes, op is '+'. What do you mean by it isn't saved anywhere?
your code just return result value,
but it should not return but save result to "this"
see example at
https://dlang.org/spec/operatoroverloading.html#index_op_assignment
I get an error, but don't understand why.
```d
auto opOpAssign(string op)(Value rhs)
{
this = this + rhs;
return this;
}
// Error: `this` is not an lvalue and cannot be modified
```
