LISP implementations invariably have a pretty printer, to neatly print
any arbitrarily complicated LISP object onto the screen.
I made a Shen pretty printer, for my work, to debug the deep learning
backpropagation program that I have been finishing. See attachment.
I sent this to the Shen gurus, and suggested, that this could be
useful for the OS Shen library.
