Another progress report: I completed regex spec support for "spec forms" feature in Reveal https://twitter.com/v1aaad/status/1429144113153183746

I like that implementing forms for regex specs made the complexity of data-driven APIs more visible. You can encode a lot using regex specs, and sometimes it's not clear what are all the possible available data shapes, and more importantly, what's the meaning (names) that's encoded with these terse data structures.

e.g. what can you pass to :require? it's called lib-spec, and it's either simple symbol — lib, or a vector of lib with opts!
