 also mention object types and value types from lisp in small pieces

-r7rs - library (C module) support is the most important, but also exceptions, improvements from r5rs, etc.

-## Interpreter
-
-used meta-circular interpreter from SICP as a starting point
+The Metacircular Evaluator from [SICP](https://mitpress.mit.edu/sicp/full-text/book/book.html) was used as a starting point for `eval`.
 
 ## Macros
 
 Chibi scheme explicit renaming macros provide an efficient place to start

 ## Future
 
 should consider optimizations from Andrew Appel's book compiling with continuations. he developed a similar compiler for Standard ML of New Jersey, which is referenced by Baker's paper.
