Could anybody explain please why I can't get a sample of falses or
quoted nils / falses here?
foo.core> (clojure-version)
"1.10.0"
foo.core> (require '[clojure.spec.gen.alpha :as gen]
'[clojure.spec.alpha :as s])
nil
foo.core> (gen/sample (s/gen #{'nil}))
Error printing return value (ExceptionInfo) at
clojure.test.check.generators/such-that-helper (generators.cljc:320).
Couldn't satisfy such-that predicate after 100 tries.
Other interesting and/or relevant cases are:
foo.core> (gen/sample (s/gen #{'n}))
(n n n n n n n n n n)
foo.core> (gen/sample (s/gen #{true}))
(true true true true true true true true true true)
foo.core> (gen/sample (s/gen #{'true}))
(true true true true true true true true true true)
foo.core> (gen/sample (s/gen #{false}))
Error printing return value (ExceptionInfo) at
clojure.test.check.generators/such-that-helper (generators.cljc:320).
Couldn't satisfy such-that predicate after 100 tries.
