13:07:15jackdanielbeach: you may be interested in this email that mentions refcounting gc: https://mailman.common-lisp.net/pipermail/pro/2020-December/001816.html -- basically it supports what you've said about such collectors
17:07:22beachMajor progress today. I fixed all the problems in phase 4 that made it impossible to load definitions of generic functions in the Ersatz environment (E5). Tomorrow, I'll attempt to load class definitions into that environment, and I'll start fixing the problems introduced in phase 4 that make that attempt unsuccessful.
17:11:30beachThe bugs that I fixed today are of the kind where you say "how can anything have worked in the past".
17:14:52beachHmm, not so good progress after all. The generic functions I load have not been properly initialized.
17:15:34beachAnyway, I am not going to attempt any more coding today. It has been a long day already.
