Is writing docstrings with argument types a thing in Python? If so, wouldn't these developers benefit from using actual type annotations (or a language with static types)? This is one area where types actually help a great deal with rapid prototyping!

Also, I disagree with the Scala examples and the argument against brevity, but I guess this is the stuff of flamewars. Not only do I not find his more verbose examples any clearer, they also lack context: presumably the full snippet looks like this:

    allClothesCount.sortBy(-_._2)

in which case any additional variable names don't help, and brevity makes the snippet clearer.
