[My ideas seem to fit well into the subject's simple (perhaps dumb) category. I hope I haven't outwore your patience.] It would seem that "global state" is the thing that needs to be dealt with first, when it comes to any thread based approaches in Emacs. I was trying to start top down, identifying the "pain points", and syntactically breaking them into a backgroundable, and non-backgroundable parts. It seems that approach can't work. Alternative one can look at things bottom up, and propagate changes in parts of the global state up the call stack. In many languages that is done using an asynchronous function and signaling protocol. Implementing something like this in Emacs, and in a staged manner that doesn't break existing code is something I would not propose without doing a lot more thought and some actual example coding. -- Barry Fishman --- via emacs-tangents mailing list (https://lists.gnu.org/mailman/listinfo/emacs-tangents)
