Why do both the method calls: sel() and self.sel() work in this code?

module Kern

  def Kern.sel
    puts "select"
  end

end


class Obj
  include Kern
end


class Test < Obj
  def method_missing(meth_sym, *args)
    puts "method missing"
  end

  def meth1
    puts "meth1"
    self.sel
  end

  def meth2
    puts "meth2"
    sel
  end
end


t = Test.new
t.meth1
t.meth2


--output:--
meth1
method missing
meth2
method missing
