Proof of concept for `(a | b).empty?` on ruby

or.rb

class Or < BasicObject
  def initialize(a, b)
    @a = a
    @b = b
  end

  def method_missing(method_name, *arguments, &block)
    @a.send(method_name, *arguments, &block) || @b.send(method_name, *arguments, &block)
  end
end

class Object
  def |(other)
    Or.new(self, other)
  end
end

username = 'sobrinho'
password = '123456'

(username | password).empty?

cool, can you really use | as the declaration of a method?
