I'm not so sure there's a huge benefit here.

my @x; $x[9] = 1; print "$#x ", scalar(@x), $/; print exists $x[2] ? 1 : 0, $/; print defined $x[2] ? 1 : 0, $/; + $x[2] = undef; print exists $x[2] ? 1 : 0, $/; print defined $x[2] ? 1 : 0, $/; ---- 9 10 0 0 1 0

Basically, all you're saying is whether that element was assigned to. That's different from "Is this index within the bounds of the array?", which is tested by if ($i <= $#array).

I shouldn't have to say this, but any code, unless otherwise stated, is untested
