+# Discussion
+
+- Q: (Referencing the first half of your talk): How does this approach
+ compare to using tq.el, Emacs\' built-in library for transaction
+ queues?
+ - A: Great question; should have mentioned that\... I took a look,
+ but chose to just do it \"by hand\"; I wouldn\'t have used many
+ of the features offerred by tq.
+- Q: Have you considered using the aio.el library (written by Chris
+ Wellons) that implements async/await for Emacs lisp using promises?
+ It\'s implemented using Elisp\'s record data structure, and turns
+ the nested callback structure into regular-looking Elisp code
+ (without extra keywords etc). +1
+ - A: I wasn\'t aware, but thanks for the pointer\-- will
+ definitely take a look
+- Q: not to take away from your excellent work, but are you aware that
+ EMMS has an MPD client? There\'s also mpc.el built into Emacs.
+ - A: Another great point; I am, along with mpdel (another MPD
+ client for Emacs). They are all full-fledge applications\-- I
+ just wanted a small, tight toolkit
+- Q:Have you seen the Lonesome Pine Specials? I saw your music library
+ and figured you would be interested. My favorite is the one with
+ Edgar Meyer, Sam Bush, Jerry Douglas, and I think Bela Fleck and
+ Mark O\'Connor?
+ - A: LOL I haven\'t, but I I think I will be!
+- Q: can you share the code to the macro that creates the callback
+ tree?
+ - A: <https://github.com/sp1ff/elmpd/blob/master/elmpd.el#L898>
+ - thanks!
+- Q: would using dynamic/special vars add anything interesting /
+ easier to async elisp in your opinion? i noticed you using \`let\` a
+ lot, but if you defined a variable hmm\... not sure if i can :)  i
+ was just wondering if having dynamic binding in Elisp opposed to
+ something like JS adds some power to async programming
+ - A: lexical binding is easier to reason about :)
+- Q: 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?
+ - A: Longer discussion in the chat room, but I think it\'s a
+ promising if over-used approach to concurrency.
