I would vote for "Stringable" because PHP already has interfaces like
Throwable, Countable, Traversable, Serializable and so on :-)

I came up with the proposal of an Arrayable interface whose intention is
in fact very close to Stringable (can be used like an array and
converted to array vs. can be converted to string)
But time doesn't seem to be ripe for Arrayable because the __toArray()
RFC isn't accepted yet and there needs to be more discussion if
Arrayable should only contain __toArray() or if it should extend from
Countable and Traversable too.
