Sort of.
You can use two namespaces to achieve this, one with the
implementation-detail functions and then another, which (ns foo (:use
...))s the first, with the public API.
People might also differ as to "natural reading order". Actually, with
factual work usually one puts the motivation first, then develops the
little things needed to eventually draw the big conclusion, and then
develops the argument and conclusion -- but also puts the
bibliography, which has the references to further sources, last.
Code generally turns that last on its head; Java also wants import
declarations at the top of the file, rather than the "bibliography"
being at the bottom. To put the "motivation" above the "argument" and
eventual "conclusion" you might want to use a comment.
