00:00:00.000 Introduction
00:21.600 How does this approach compare to using tq.el, Emacs' built-in library for transaction queues?
01:10.480 Have you considered using the aio.el library (written by Chris Wellons) that implements async/await for Emacs lisp using promises?
02:45.440 Are you aware that EMMS has an MPD client? There's also mpc.el built into Emacs.
05:20.360 Have you seen the Lonesome Pine Specials?
07:44.400 Would using dynamic/special vars add anything interesting / easier to async elisp in your opinion?
10:16.560 How does your project compare to some of the other MPD clients?
11:55.040 Can you share the code to the macro that creates the callback tree?
14:42.880 There's another package (chuntaro?) in addition to wellon's aio that also implements a coroutine trampoline on the emacs event loop. any thoughts on the async/await paradigm generally red/blue functions, etc?
15:03.440 Any thoughts on the async await paradigm generally, red-blue functions, etc.?
21:06.320 Do you think it's a viable future for Emacs to get out of callback hell?
