Turns out, I'll kill myself before writing a Prebirth compiler in a
block-define-based Prebirth Lisp. So, let's degrade even further into a
primitive Scheme. This is going down a dangerous path to simply
implementing Scheme...
Nonetheless, here I remove `define-block' in favor of a simple shorthand
function definition `define', as is custom in Scheme. We will worry
about block definitions later as metadata mapping to normal functions.
This is hopefully the beginning of a good thing that I'll actually
finish. I began planning this project formally just before the beginning of
Aug 2017.
