# frozen_string_literal: true
class Module
# A module may or may not have a name.
#
# module M; end
# M.name # => "M"
#
# m = Module.new
# m.name # => nil
#
# +anonymous?+ method returns true if module does not have a name, false otherwise:
#
# Module.new.anonymous? # => true
#
# module M; end
# M.anonymous? # => false
#
# A module gets a name when it is first assigned to a constant. Either
# via the +module+ or +class+ keyword or by an explicit assignment:
#
# m = Module.new # creates an anonymous module
# m.anonymous? # => true
# M = m # m gets a name here as a side-effect
# m.name # => "M"
# m.anonymous? # => false
