It's not quite the same ^^. @rv is an array and in scalar context evaluates to the number of the emelents. Slicing turns it into a list and thus gives the last element instead.

use strict; use warnings; print "Just Another Perl Hacker\n";

Is the behavior of list slice subroutine return an intended feature, is it specced somewhere (or even documented)? Or is it just an implementation detail which might some day be considered a bug and be changed thereafter?

Don't golf production code ;-)
