Thanks @dominicm for the pointer. Looks great, seems to lean on custom strict-keys Spec to catch the typos. Coudn’t get it working as it uses really old version of spec, but will poke around to see if I could get it working. Different artifact name btw in Clojars and in Github.

Hi everyone- I have a clojure DSL that comes in two variants that are about 95% the same and I want to write a single spec that validates both variants- What is the best way of doing this? Basically what I want to do is write about a hundred clojure.spec/def declarations that are the same for both variants, but a few deeply nested items will need idiosyncratic logic, looking something like:

(s/def :deeply/nested-item
     (if variant1? 
          variant-1-specification
          variant-2-specification))

aaron brooks was just talking to me on twitter about this sort of thing

@gfredericks yep, that's my situation...

yes, I think I'll just use @abrooks' cheat until "spec specs" are available- Thanks for the pointer!
