Yeah I was referring to something similar to what C# has (aside from the
lack of boxing).

Why would they need to be virtual? They obviously aren't in C#, but they
still work pretty well (e.g. foreach loops work with List<T>.Enumerator,
which is a struct but which can be treated as the IEnumerator<T>
interface), right?
He must be referring to nominal conformance. It's been discussed many
times. There are important disadvantages (e.g. you can't "implement" a
type alias) but there are advantages too.
Ultimately we never got around to it.

Haha ok, that's a good reason in its own way, thanks. :)
