I haven't been following the other discussion, but I think deprecating dolist
is a little extreme. I use dolist a lot because it makes a lot of things I
write a lot simpler (over using the loop macro or mapcar).

I suspect a lot of existing code out there uses dolist, a github search
suggests about 500k uses (although many of those are probably copies).
