[Daniel Steinberg]

I agree - there are a few I'd love to see discussed.

I also agree that I appreciate that they are there and so well thought out and presented

For example, I totally agree with Erica’s suggestion that all methods with side effects should be verbs, not just ones that mutate the receiver.
