--- Comment #1 from Abel Braaksma <abel.braaksma@xs4all.nl> ---
While I am not unsympathetic towards the proposed change, the original function
shows the recursive nature and is a common way in functional languages to
describe such higher order functions, this can be seen in many text books. 

Furthermore, I think it is good to show the tail-recursion, which is not
present in the map operator (though it begs the question, is the current
signature truly tail-recursive? I don't think so, as there is an embedded
function call in the final fn:for-each call, a let-return statement would
perhaps be better).
