We support any super type of anything that we can serialize. Meaning
that as long as the Type that's passed through is less precise, it means
that we can encoded it as any subtype and therefore the incoming type
doesn't have to be the subtype in that case. Basically, as long as
you're only passing through an `Iterable<T>` in TypeScript, then you can
pass any `Iterable<T>` and we'll treat it as an array.
For example we support Promises *and* Thenables but both are encoded as
Promises.
We support Arrays and since Arrays are also Iterables, we can support
Iterables.
