While I suspect this can be fixed (and is missing setup of the auto-viv
callback on the codepath for setting up a default), note that `is default` is a
trait, it is evaluated at compile time. Thus there is one single array that
will be shared globally and assigned into all elements, which probably isn't
what you wanted.
