Not built into Ruby, true. But an app might have its own meta-data, possibly
domain-specific. Perhaps things like param types, or data about how
parameters are interpreted by a method (e.g. "either a list of dates, or a
start date and a list of durations "), etc. A domain-specific Ruby could add
Class#methods to declare such things.
