That is why it is smart to communicate small non essential changes: people
can set you on the right track. :-)
I put that back. I now removed the ‘:aot [quotes.core]’, or should I keep
that also?
When I first got the error I found two different pieces of advice. One for
both changes. When those did not work I asked here.
I should pick up Clojure again. I only did one little project (long ago) to
try it out. But that is no way to learn a language. Sadly there is no real
use here for it. :'-(
