attempt-allcljmacro
(attempt-all bindings return)(attempt-all bindings return else)Used like let, but short-circuits in case of
a failed binding. Can be used in combination with when-failed
to handle the failure.
Unlike let, only accepts a single form to execute after the bindings.
(attempt-all [x "Ok" y (fail "Fail")] x (when-failed [e] (message e))) ; => "Fail"
