On the first point (spaces vs no spaces, I changed it now to say that either way is fine. I really think it is fine, though perhaps it's a little weird to have a style guide that says "either way is fine", not sure. We can talk about it next time.

Disagree on avoiding default parameters.

Also, it's true that `Long Parameter List` is a smell, but whenever possible I'd prefer to reduce the number of arguments altogether. Using a hash instead is often just a bandaid (though not always).

Leaving it up in the air for now.
