Good, thanks!

The current interpeter I consider to be a prototype in C; I use gcc.
However, HACKING mentions two ways forward
** Move mes.c into hex?
One idea is to use OrianJ's amazing self-hosting
[[https://github.com/oriansj/stage0][stage0]] hex assembler and
minimal bootstrap binaries and rewrite the mes.c core to directly
bootstrap into Scheme.
** Rewrite mes.c and generate hex?
Another idea (thanks Rutger!) is to rewrite the mes.c core in a
C/Assembly variant and have mescc produce the simple, annotated
bootstrap binary.
Possibly you have an even better idea? I am choosing to explore the
latter first: work on the compiler backend and write the interpreter in
its Assembly/C-like s-expressions.
