Ah yes, Robert has a knack for joining cool communities 
(heās been an Admin on the Elixir Forum since pretty much the beginning!). We also have Bjƶrn Gustavsson here too (member of the Erlang Core Team) as well as other famous Erlangers like Fred Hebert.
Unfortunately I havenāt had much time to read more, so what I think I might do is rather than just do one post per chapter, Iāll post whenever I encounter something of interest too - thatāll hopefully mean more frequent posts from me and mean you wonāt be as lonely in this thread, haha 
With that in mind, I just posted a thread about something that cropped up in this book!
I am going to start saying unpacking moving forward, Joeās exact words were: āThen weāre going to unpack these data structures and extractā¦ā 
Thereās so much in this chapter Iāve already highlighted and Iāve only just started it!! Iām really loving this book!
LOVE how easy it is to test right there in your module! (Loved this when I first saw it in Elixir too, but itās even simpler in Erlang!)
LOVE how Joe explains the grammar: commas, semicolons, and periods.
Canāt wait to read more, and glad to see you are progressing well - the fact that you are is helping ensure I keep at it as I donāt want to fall too far behind, so thank you
