Bump on this topic as I would like to hear some feedback.

As a clarification, the current implementation of the PR affects arrays in
general, not only array_fill. Any array that starts with a negative index
would continue from that index instead of 0. Meaning that [-2 =3D> true,
true, true] would now return [-2 =3D> true, -1 =3D> true, 0 =3D> true] inst=
ead of
[-2 =3D> true, 0 =3D> true, 1 =3D> true].

Regards,
Pedro
