returnclj

(return v)

Creates a flow that returns v. Use this as the last step in a flow that you want to reuse in other flows, in order to clarify the return value, e.g.

(def increment-count (flow "increments :count and returns it" (state/modify update :count inc) [new-count (state/gets :count)] (state-flow/return new-count)))
