defined¶ ↑

Calls Module#defined after a class or module has been defined or redefined

Note: relies on {Kernel#set_trace_func}[http://www.ruby-doc.org/core/classes/Kernel.html#M001430]

• Fork the project.

• Make your feature addition or bug fix.

• Add tests for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with Rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

• Send me a pull request. Bonus points for topic branches.
