We'll start with a function that logs the output of calls to Array.prototype.slice; starting from 0 up until n (number of agruments).

function logArgs () {
  var length = arguments.length, args;

  for(var index = 0; index < length; index++) {
 args = Array.prototype.slice.call(arguments, index);

class HiO
  def print_i
    # note...this won't print 12...even though we set
    # this variable in the `toast` method
    puts "my var is #{@var}"

    # and neither will this...failure!!!
