in reply to Last Element of Hash

I was thinking something like:

my @elements = ( keys %hash );
foreach (@elements){
  if ( $_ eq $elements[-1] ){
    #Do something to last element
  }else{
    #Do something to an item in element
  }
}

To me, it's easier to see it that way... I'm still rather "young" on Perl :-)
caveat: above will give warnings if @elements is full of numbers...

Update: Changed @elements[-1] to $elements[-1]

    No it won't. You can always use a number as a string without any warning. The reverse isn't always true.

    And besides, here, the elements are originally hash keys. Hash keys are always strings.

      Thanks for the clarification... I still get confused sometimes over the little details, but I'm slowly getting the hang of it :-)
