require 'did-you-mean'

["downcase", "downcase!", "swapcase", "upcase", "concat", "swapcase!"]

# Avoiding NoMethodError on method_missing

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.
