====== Perl Notes ======

===== Special Variables =====
  * @_ - any arguments passed to a subroutine are accessible with this variable

===== Lists, Arrays, and Hashes =====
  * $var is a scalar
  * (8, $a, 0.4, 'test') is a list (used to create arrays, etc...)
  * @var is an array
    * $var[0] is the first item in the array
  * %var is a hash
    * $var{key} is the value of the item with "key"
