# This should look in a master Extensions module
# instead of the class/modules themselves.
# B/c this way thay can be loaded via the same file.
# Example:
# # string/align.rb
# class String
# module Align
# def align_center
# ...
# end
# end
# end
# With this one would have to have a separate require that
# include the Align module into Strin gautomatically (or
# else alwys do it by hand *ick*). But if we just had:
# # string/align.rb
# class String
# def align_center
# ...
# end
# end
# Then we can use module_require to load this in a mater
# extensions module. And #express could just use that.
module Kernel
# Extend an object with an internal
# extension module.
#
# class Array
# module Random
# def shuffle
# [] # ...
# end
# # ...
# end
# end
#
# a = [1,2,3]
# a.shuffle #=> NoMethodError
# a.express(:Random)
# a.shuffle #=> []
def express(name)
extend self.class.const_get(name.to_s.capitalize)
