Returns nested module as an array of Module objects:

Example

module M0
  def self.speak = Module.nesting
  module M1
    def self.speak = Module.nesting
    module M2
      def self.speak = Module.nesting
    end
  end
end
M0.speak             # => [M0]
M0.speak.first.class # => Module
M0::M1.speak         # => [M0::M1, M0]
M0::M1::M2.speak     # => [M0::M1::M2, M0::M1, M0]
