Description

There are many occurrences of reflection in the pprint implementation.

By eliminating all of them, I ran one benchmark of pprint'ing a Clojure map that resulted in a 300 Kbyte output. After eliminating reflection, the elapsed time to pprint was reduced by 18% (about 14.0 sec down to about 11.5 sec) on a recent model MacBook Pro.
