Update: I didn't read your post carefully enough

You get the result you want, but the semantic is not what you indicate by using exists so I'd rather use defined in that case.

#! perl use warnings; use strict; my @x = (1,2,3,4,5); delete $x[2]; for (0..4) { print $x[$_] }
Run it to produce:
Use of uninitialized value in print at line 6. 1245
So, the element exists, but it's value is undefined.
