for the first element you could "peek" like:
$first = $array[0];
for the last element you could "peek" like:
$last = $array[$#array];
$# indexes the last element of the array. just make sure you use the same
array's name in the index

I suppose I could do something like:
my $check_me = pop @array;
push @array, $ch

In case anyone is wondering why I want to do this, I am running through
an array (popping out all elements) in order. Some things from the
array act differently depending on what is left or right of them (if I'm
shifting or popping respectively). I want to double check before I pop
or shift.

How about:
my $check_first = $array[0];
my $check_last = $array[-1];

Is there a way to "peek
Is there a way to "peek" at the top or bottom of an array? Sort of like
pop or shift but without needing to insert the value back into the
array?
I suppose I could do something like:
my $check_me = pop @array;
push @array, $check_me;
But that seems kind of inelegant and verbose.
Thanks,
Dan
