So far it works pretty good. Minor edits I just quickly edit and tangle, otherwise I open the source block in a buffer (C-c '), and from there I can just use the usual C-c C-c shortcut to send it to the REPL.

But as the first stage bootstrap in CL is mostly done at this point, I have to hot-reload anyway.

At some point it might be nice to have my own REPL running in Emacs, but that is a worry for way later when I actually get something usable. For now this is purely for personal entertainment.
