negative indices

[Jerrad Pierce]

I was wondering if perl would be handling negative array indices in the
same manner as perl 5?
That is to FETCHSIZE + index = real index, before attempting to fetch
the element.
It would be swell if the index was passed along as negative, and to then
have the guts do
this voodoo. This way, one could tie an array to Class which used two
arrays to emulate real
negative indices (as opposed to count from the back).
