Hi all. I'm wondering about the best way to document the relationship between a spec and a binding 📚 • I have a spec (s/def ::factor (some-predicates-here)) . • ...and I have a default db in a re-frame app : (def default-db {:some-key nil}) . • I want to communicate that :some-key is supposed to adhere to the ::factor spec, for myself and other people reading the code in the future. • I tried using metadata (def default-db {:some-key ^spec:factor nil}) but nil can't receive metadata. • I'm doing validation with (valid?... ; my question is just about documenting the relationship. • A comment is better than nothing but I'm wondering if there's a better, more idiomatic way. What's the best way to do this? 👀
