I couldn't agree more. Thank you Chris!

Hi there! I have a question about raising NotImplementedError.

I see "raise NotImplementedError" in the abstract class, but some people suggest not to use it. Instead, they add documentation and remove the methods. However, I think raising error in abstract methods is beneficial to those who use IDEs such as RubyMine to increase productivity with its code completion and inspection for method existance.

Could you share your opinions on which approach to use?
