I saw this message by you, Alex, on a Reddit discussion: https://www.reddit.com/r/Clojure/comments/8i3hh0/what_is_the_future_of_clojure_in_the_industry/dysixcn/

Would adding the links you gave for Cognitect blog articles on spec, and the videos, to one or both of the spec rationale and spec guide articles be of interest?

I have read about some operation in spec doing 'sampling' in its validation/checking of a value against the spec, for better performance (but also, obviously, less precise checking). Is there something in the spec documentation I can look for to remind me where this occurs?

s/every and s/every-kv

Thanks. I see those in the spec guide, and good to see the doc strings for s/every and s/every-kv mention that partial checking property.
