If the list is named @array, you can find the last element with $#array.
Consider the following code:
my @array = qw/this that the other/;
local $, = ", ";
print @array[1..$#array], "\n";
__OUTPUT__
that, the, other
An unnamed true list (one that isn't held within a scalar in any way, nor referenced by an array-ref) can't be indexed in such a way as to construct a 0..end-of-list, but you do have a couple of other options.
my $last_item = (this, that, the, other)[-1];
Or the more useful...
my $list = [qw/this that the other/];
local $, = ", ";
print @{$list}[0..$#{$list}];
This last alternative uses an anonymous list referred to by an array-ref scalar.
