Clojure's automatic gensym feature in defmacro is similar to the idea

it's not historically originated by Hoyte as similar ideas have been

Sometimes it is useful to have a referentially opaque symbol that you can
refer to when calling a macro. Clojure's design encourages the idiom of let
bindings instead of anaphora to maintain referential transparency, but in
some cases it is preferable to capture a symbol and make use of it. If

A related problem occurs when you separate your code into multiple

One way to approve the problem is to write a function to convert the nested
maps into nested seqs. Once it is in that form you can use flatten on it and
partition the flat list as you like:
(defn flatten-maptree [m]
(letfn [(maptree-seqtree

That is, had flattening actually been your goal. It seem like you didn't
really want to throw out that structure, just transform it, so flattening is
