ELS 2024 in Vienna

I just got back from the 2024 European Lisp Symposium in Vienna. After many years it was good to meet again in person with so many talented and interesting people (all interested in parentheses).

Many, many thanks to Beppe Attardi, Philipp Marek, Georgiy Tugai, Yukari Hafner, and, especially, Didier Verna, for pulling this together.
