Nope. I moved the main code to ns hexadoku.core (generating package

I'm using Clojure to generate java source (enums, specifically) and am

Currently my generator consists of a collection of function which call
each other tree-recursion-like.

Each function takes a map of input. Much of this is constant for any

For interfacing with some Java code I need to create an empty string

So I have come up with a solution to my desire to move to defprotocol/
type in spite of my requirement for gen-class' init/post-init
methods :
(def protocol Resource
(open [this])
(close [this])
...
)
(deftype ResourceImpl [resource]
Resource
(open [this]...)
(close [this] (.close resource).
