p=fn 0,_->;i,p->spawn fn->w=" on the wall.";b=&" #{&1} bottle#{&1==1&&""||"s"} of Elixir"
IO.puts [inspect(self),b.(i),w,b.(i),".\n",i==1&&"Go get some more,"<>b.(99)||"Take one down pass it around,"<>b.(i-1),w,10]
p.(i-1,p)end end;p.(99,p);:timer.sleep 999

Note: the sleep call at the end feels like cheating. I had a prior solution in which the main process received the verse string from each spawned process and then printed it itself. That was well over 300 chars though.

Nice solution! Here are a few ideas for improvement:

• You can replace ".\n" with a plain newline (1 char less)
• Maybe you did it on purpose, but the semicolons are not really necessary. You could just replace them with plain newlines as well to make it (imho) a little bit more readable. But again, maybe that's not the point ;-)
• You can replace i==1 with i<2 or i>1 and flip the branches (two occurrences, so 2 chars less)
• You can replace sleep 999 with sleep ?ϧ (1 char less) I learned this technique from @henrik's solution to the last elixir golf. Basically you can find the appropriate unicode character by running to_string [999] in iex.

Thanks for your reply @padde Once I saw that I was 30 chars behind @henrik I stopped trying to micro optimize

• :-) Yes, I used semicolons instead of newlines to make it look more imposing 👿
• That sleep ?= trick is one I hadn't thought of before
