Feature request: enum value descriptions

Sometimes, the enumerated values are not clear enough by themselves. It would be nice to have a standard way to provide a description for each enumerated value.

Following our discussion on Slack, a nice solution would be to have :enumn (similar to :catn) that support description of enumerated values, like this:

[:enumn 
   ["foo" {:description "foo means that you don't know how to name things"}] 
   ["bar"] 
   "baz"]

Where some enumerated values have description and some don't.

Open question

Is there a way to pass the description of enumerated values to Swagger? JSON Schema doesn't seem to support description for enumerated values.
