How much work does defining a type do at runtime?

eg, is it likely to be a performance issue to call

type('string.json.parse').pipe(MyPayload)(body)

type('string.json.parse').pipe(MyPayload)(body)

on every message we want to parse vs saving the functoin somewhere, or is it pretty lightweight? (Yeah, I can benchmark

but wondering if there's a recommendation.)
