A nicer equivalent form would be: (cond-> [] this-error? (conj “It failed with this error”) that-error? (conj “It failed with that error”))
However, purely for validation there are a few utilities out there already. Checkout the ‘Validation’ section on http://www.clojure-toolbox.com <http://www.clojure-toolbox.com/> Also, in terms of enforcing contracts - Prismatic Schema is highly recommended but hard to ‘englishify’ the errors. Failures are considered API failures rather than happy-case failures. > On 12 Nov 2015, at 16:09, Brian Forester <brian.fores...@gmail.com> wrote: > > I'm writing a very small REST application in clojure using compojure and > ring.
