module Concurrent
# Methods form module A included to a module B, which is already included into class C,
# will not be visible in the C class. If this module is extended to B then A's methods
# are correctly made visible to C.

# @example
# module A
# def a
# :a
# end
# end

# module B1
# end
#
# class C1
# include B1

# module B2
# extend Concurrent::ReInclude

# include B2

# B1.send :include, A
# B2.send :include, A

# C1.new.respond_to? :a # => false
