I would like to have a better solution for this problem: https://github.com/borkdude/speculative/issues/276

Is there something like s/undef in spec? I guess not?

IIRC there’s a ticket for that

What I actually want is to define a an fdef that doesn’t get instrumented when calling (stest/instrument), but this may be too niche.

I had this ticket in mind: https://dev.clojure.org/jira/browse/CLJ-2060

oooh, nice 🙂

this is already in spec

but this doesn’t work for fdef?

(s/def clojure.core/hash-map nil) works

seems to work also in CLJS

would expect fdef’s to be put in the registry

cool, I might be able to use this, thanks @eval2020!
