doc string for reify is missing a statement of what it does
While the doc string for the function reify is quite detailed, it never seems to say what it does. The addition of a single sentence near the beginning of the doc string, perhaps one similar to the following, would help:
"reify defines an anonymous type, and creates and returns an instance of that type."
Note: The reference documentation for reify on clojure.org is better in this regard https://clojure.org/reference/datatypes#_reify and I copied then edited one of the sentences there to create the one proposed above.
