Feature #5899: chaining comparsions.

Target version: 


Migration from python to ruby is problematic because ruby lacks certain features.
Most important python advantage is chained comparison
We must wrap every comparison like described below.

puts "yes" if 1<2<3<4

class Fixnum
  def <(a)
    ((self<=>a)==-1)&&a
  end
end
class FalseClass
  def <(a)
    false
  end
end
