No implementation of method: :< of protocol: #'tick.core/ITimeComparison found for class: nil
Because: tick.interval/relation cannot handle nil, which it will get in the example above.
I worked around it by doing:
(defn safe-concur
([] nil)
([x] x)
([x & args]
(reduce
(fn safe-concur-check [x y]
(and
(and x y)
(tick.interval/concur x y)))
x args)))
