Subject: a method that checks if an object is in a range

Hi,

I wonder if there is a built-in method which does just like:

  range.include?(obj)

but for the obj object. I came up with something like:

  module Comparable
    def in?(range)
      range.in?(self)
    end
  end

  1.in? (1..10) # => true

Of course I can use the range.include? syntax, but I find the second
approach more convenient :)
