This is a good idea... They could yield something like:

  >> map
  (function(f:(function(x:type)), xs:{type}) PRIMITIVE)

I.e., they report the type signature.

However, as Steve pointed out, it could be hard to accomplish.
Also, what to report when we have ad-hoc polymorphic functions,
where there are several implementations with different type
