Thanks to @tehviking and his 2014 Rubyconf talk. Sometimes when working on a C extension you sometimes need some affirmations in your irb. I've tried to provide that for him.

$ gem install irb_affirmations

Add this line to your .irbrc:

require 'irb_affirmations'

1. Fork it ( https://github.com/adkron/irb_affirmations/fork )
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create a new Pull Request
