Comment (by spacedmonkey):

 That was going to be a my next question.

 Should the default value, obey the `single` an `type` definitions? Should
 be cast the default value, to make sure it returns the right type. Say
 make sure it is returning a number instead an array for example.

 It also seems like the rest api has decided for us, by only allowing a
 single value to returned as a default. See

 line].
