Proposed change to Module#is

Here’s the change to #is I’ve been contemplating. I’m thinking it
might make a good override of include actually.

class Module

def is(*mods)
  mods.each do |mod|
    if mod.const_defined?(:Self)
      extend mod.const_get(:Self)
    end
  end
  include(*mods)
end

end

example:

module Dog

def bark; "ruff"; end

module Self
  def fleas; '. ' * rand(10).to_i; end
end

end

class Spot
is Dog
end

Spot.fleas #=> '. . . . . ’
