I don’t know if you’re aware, but you can extend arbitrary nominal types with
literal syntax.
```
extension FixedSizedArray: ExpressibleAsDictionaryLiteral { … }
```
Nothing special needs to be done on the implementation side to make this
possible. If fixed sized arrays are not nominal types (like tuples, unlike
`Array`s), then you will only be able to give this sugar to types that wrap
them, not the type itself (w/o special support).
What’s the discussion on enhanced array and dictionary literals? I think I
missed that.
