Function clojure.spec.test.alpha/check silently ignores symbols which are not "checkable". This seems counter-intuitive to me because I'd expect it to fail when I call check on a symbol and the symbol does not have a spec (e.g. it is misspelled).
The definition of check looks like this:
( (check (checkable-syms)))
([sym-or-syms] (check sym-or-syms nil))
(->> (collectionize sym-or-syms)
(filter (checkable-syms opts))
#(check-1 (sym->check-map %) opts)))))
It seems to me that the (filter (checkable-syms opts)) might better go to the no-arg variant.
