I suppose we always prefer to move *all* data into databases or files with
dedicated data formats, *including* arrays, strings, dictionaries, etc. Sure.
But it would be rather underwhelming if you could not also just instantiate an
array or a string from a literal.

I agree, except, something like `[1, [2]]` doesn’t immediately strike me by its
complexity. Likewise, I find it a little deflating that I cannot express a
piece of JSON in code. My example structures do allow you to write:
let _: DictionaryTree<String, String> =
[
"name": ◊"Johnny Appleseed",
"address": [
"streetAddress": ◊"21 2nd Street",
"city": ◊"New York"
]
]
… but I cannot get rid of that prefix operator without the additional
literal-convertible protocols. Given the *simplicity* of these structures, it
seems it should not be beyond Swift to represent them in code with ease and
elegance. And to begin with, all we need are those couple of protocols.
