Add guidance for safe navigation operator (`&.`)

Open andyw8 opened this issue 4 years ago • 1 comments

Reading https://thoughtbot.com/blog/ruby-safe-navigation reminded me that over-use of &. is common. I think it would be helpful to add a guideline such as:

Avoid long chains of &.. Replace with . if they introduce unnecessary conditional logic. Consider other approaches such as delegation.

This could also be added as a rule in RuboCop with a maximum number of chained calls (e.g. 2 or 3).
