Horizon Transaction First Draft

The :hub is the transaction and/or application (more on this later). Each :node is wrapper around a Hero Formula responsible for passing the non-boolean values to the :hub, but it also returns a boolean. Each camel-cased line inside the :node parentheses is a Hero :formula and the values in quotes are the return values of a Formula's :step. Formula.step is the only thing responsible for changing state.

The following is in Clojure but it should be interpretable from a Ruby perspective; it's the relations that matter here not the syntax.

[:hub ;; begin transaction
 ( ;; begin set of Nodes
You can’t perform that action at this time.
