From that chapter:

> If a function only transforms data, we should avoid verbs wherever possible.

This is a rule I use, but was not aware of until just now. Thank you.

I don't write much Clojure, but I found that chapter worthwhile.

The concept of the "sense" of a sign is very elegant.

The name of this books is really confusing. Unfortunately, most developers would skip it. But this book (largely) is not about Clojure.
