--- Comment #1 from Steven Schveighoffer <schveiguy at yahoo.com> ---
Works as designed. As I mentioned in the forum thread, when you override one
overload of a base function, you override them all. With classes, you can alias
in the base class definitions of the function, but with alias this, that is not
an option (there will be a `this` type mismatch).

The workaround is to forward the other overloads back to the base.

e.g.:

auto opAssign(int x) { return a.opAssign(x); }
