Subject: [ruby-core:44014] [ruby-trunk - Feature #5899][Feedback] chaining comparsions.


Issue #5899 has been updated by matz (Yukihiro Matsumoto).

Status changed from Assigned to Feedback

I don't think changing "1 < b < 4" to "1 < b && b < 4" is that hard task.
I am not sure it's worth allowing confusing "false < 4".

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
