Can you guess how long they should take to implement?

Uh, yeah you can. Haskell can have variadic functions, like
Text.Printf.printf, and with some explicit type signatures you can
still partially apply it.

In Haskell, it's simple to explicitly state what names should be
exported by a module. Is there a way to do this in Clojure?

Example:
(def add5 ($ + 5))
(add5 3)
Beware! For this macro evaluates the later parameters before the
partially-applied ones, so side-effectful parameters may occu
If not, I think it's pretty useful. There should be an easy way to
apply functions to maps' values by keys.
