I have mentioned that in the RFC, see [alternatives

section.
I think the builtin template is better because it:
- provides the most obvious semantics for type aliases and avoids confusion,
- avoids the need for instantiation of the underlying template with
non-duplicated list types,
- is simpler to implement.
