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.
