On a positive note, AOP with mixins just got way simpler in Ruby 2:
Raw
module_prepend.rb
module Helper
def help
puts "Hello,"
super
end
end
class Foo
def help
puts "Do you need help?"
end
end
Foo.send(:prepend, Helper)
Foo.new.help
__DATA__
Prints:
Hello,
Do you need help?

prepend is rad.

(I also continue to love Ruby’s __DATA__ declaration.)
