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

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
