I’m sorry for the confusion. There are two issues: whether it is important to highlight word boundaries, and if so, what approach to use. The first (and longer) part of the email was intended to justify why we don’t highlight word boundaries for keywords. My overly snarky answer at the end was an attempt to answer why we don’t use snake case, but it wasn’t very effective :-) Here is a different way to look at it: if we were going to highlight word boundaries, we would do it with camel case. We use camel case in other places, and it has advantages over snake case (shorter identifiers), so we wouldn’t introduce a new way to do it. > As for snake case being ugly, my mileage does vary (obviously).

The short version of the argument is that multiword keywords and declmodifiers are rare , primitive, and used in idiomatic ways so the opportunity for confusion is low. -Chris
