 03:01.480 Q: About fibers: My understanding is that the problem with making Elisp concurrent is that none of the data structures (buffer, cons, vector, window etc) are concurrency-safe.  How do fibers help with this?

 06:19.240 Q: A Common Lisp implementation for Guile sounds really cool! Is there already work on this underway?
