#    Adjusted to use Tuple::[] instead of ::new, which now takes a single
#    argument, either an Array or a String which it splits.

#:title: Tuple
#
# A Tuple is essentially an Array that is also Comaparable.
#
# == Usage
#
#   t1 = Tuple[1,2,3]
#   t2 = Tuple[2,3,4]
#
#   t1 < t2   #=> true
#   t1 > t2   #=> false
#
class Tuple < Array

    new(args)

    when String
      if md = /([-.,;:'\\\/])/.match(arg)

      self.concat arg.split(/([-.,;:'\\\/])/)
