I think literal arrays are always immutable, and one could base the test on
that.
Is such a function useful in some other context? If one has an array which is
already immutable, it can be referenced freely and copying it seems
unnecessary. If one has a mutable array, is there any reason why one would want
to make an immutable copy?
