That's true: my Grandfather programmed it decades ago.
So can Prolog.
But is it relevant?!

One approach to having a true-negative indexed array is by defining
an object-oriented approach. A set of tied-array-based methods might
provide the most natural approach. That should allow a transparent mapping
of negative array indices onto a perl zero based array implementation
while avoiding a
big pain when you could just use a hash.

I do not want $#_-10, I want literally $_[-10].
What's the difference which way it is if you access it only by
using negative offsets ?
Not *only* negative offsets.
In other words:
