Maru - a tiny self-hosting lisp dialect

[Scott McKay]

Nice work. It's worth the extra length in order to buy correctness and
portability
that you yourself don't have to maintain.

Lisp is the simplest language to bootstrap for sure. Would be nice to get
everything
out of the bootstrapper that isn't the core Lisp language. Of course, it's
probably worth
having handcrafted LLVM code for the primitives that greatly affect
performance.
