The difficulty I'm having is figuring out how to then embed these schemas
into another schema. (The reason I want *that* is because these steps are
composed into different schemas, and I'd like to check the superschema.)
Ideally I would end up with something like:
(def Step
(s/conditional
#(= (:type %) :http) {:the :http :schema :here}
#(= (:type %) :delay) {:the :delay :schema: :here}))
... except with the keys and schemas coming out of the multimethod (or
whatever) instead of being a literal :)
I guess I could do that with some extended macrology hackery for now; if my
defstep macro stashes all of the schemas in a ref somewhere, I can then
expand to the above code example :)
I've created a ticket for this on prismatic/schema:

thanks again,
lvh
