Early on, I started doing an incomplete implementation of Arc more like what one of the parent comments suggested, and the working title was "morc: Mock Arc Programming Language as Scheme Extension". I just wanted to learn Arc, while learning Scheme macros better.
Besides possibly adding to the confusion over the relationship between Arc and Racket (or PLT Scheme), my poor choice of title caused at least one community member to be upset, that I would mock (insult) Arc. When I meant only to be self-deprecating of my own exercise, like a poor-imitation or approximation, and not to seem to presume to be implementing a full Arc this way.
