It appears that closed spec checking doesn't work on select in spec2. Is this something deliberate?

don't remember :) I think it should work? but could easily be buggy

Toy example:

(spec/def ::a string?)

(spec/def ::s (spec/schema [::a]))

(spec/valid? ::s {::a "hello" ::b "world"} {:closed #{::s}}) ;; => false

(spec/valid? (spec/select ::s [*]) {::a "hello" ::b "world"} {:closed #{::s}}) ;; => true

I read through the implementation of select and it looks like it doesn't do anything with :closed

the things you "close" are schemas

select has some pending rework to make it build more on top of schema

when that's done it should start getting that effect

so without thinking more, this is probably in the category of wip

Ok, thanks for the clarification! Sounds also like it would not be fruitful for me to submit a patch, also, so I'll wait on it

nah, it's a non-trivial amount of work and bound into other things
