    @ARGV
    
    The array @ARGV contains the command-line arguments intended for the s
    +cript. $#ARGV is generally the number of arguments minus one, because
    + $ARGV[0] is the first argument, not the program's command name itsel
    +f. See $0 for the command name.

[sierpinski]: I've never seen $#$var before.
[LanX]: $list cops be an array ref
[LanX]: could
[LanX]: $#array gives the length
[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?
