[LanX]: no sorry ...
[sierpinski]: so that would just be deferencing it...
[LanX]: the last index!
[LanX]: yes
[sierpinski]: yeah I guess $list is a reference.. yeah
[sierpinski]: why is it the last index and not the first? because the length of the array becomes the index?
[sierpinski]: thanks LanX that helps
[haukex]: the first index is always 0 - $#array gives you the last index in @array
[sierpinski]: gotcha, thanks
[LanX]: length = last index +1
