;; Transparent Functions

;; I was experimenting with transducers and wanted a way to understand how they worked. Transducer
;; code uses many nested functions in various locations with other nested functions defined as local
;; variables in scope. Typically after an anonymous Clojure function is defined you have no visibility
;; into the locals that were in scope when the function was defined, where the function came from,
;; or the code in the function. I defined a macro, tfn, that creates a transparent function. It's 
;; a normal Clojure function with additional metadata including the function code and local 
;; variable names and values.
