Things like "super.tap" make me think I'm about to go on a wild goose chase.

  It's pretty simple and useful; instead of def my_method super_result = super ... (do something with super_result, or simply after super has been called) ... super_result <== to make sure your method returns the result of super end you can just do this: def my_method super.tap{|result| (do something with/after result) } <== will still return the result of super end

    Tap is by far my favorite method though usually on hashes to add conditionals

    I know what it does, but isn't it (and your examples) an instance of the Call Super[1] antipattern? 1. https://www.martinfowler.com/bliki/CallSuper.html https://www.martinfowler.com/bliki/CallSuper.html

      From my understanding, the anti-pattern is related to creating an API that requires a call to super when overriding a method. super.tap may be used when interacting with an API that employs the "call super" anti-pattern, but calling super is not itself an instance of the anti-pattern; it can be used in perfectly legitimate cases as well.
