Hello All!

I am trying to implement my own Design Patterns Library.


If you are talking about a code library (as opposed to a library of documents) then I'd like to discourage you. Design Patterns are not the kind of thing that you can turn into a reusable coding library.

Observer is one of the exceptions to this rule; but it's only a partial exception for the reasons that you have already pointed out in your post.

# Ruby
require 'singleton'
class Logger
include Singleton
end

Logger is now a singleton class. Is that one of the exceptions?
