(I don't see what this has to do with atexit, but never mind that.) The current situation is that: - Guile's objection is encoded: - primarily in the throw key (a symbol) that is the first arg passed to the catch handler, e.g. 'misc-error - secondarily in the remaining throw args, in a way which is key-dependent and very poorly documented - the location where the problem arose is not supplied by default, but can be found out by capturing the current stack - (make-stack #t) - in a lazy-catch handler. My impression from various emails is that there may be issues with this model, so my purpose here is to explore whether there are issues and, if so, to address them. So, given this description, can you be more precise about which (if any) parts of it are causing you trouble?
