The issue here is that `case` does not actually evaluate the datum parts of each clause, instead essentially just `quote`ing them and matching on that. So effectively you are matching on the datum `(quote (hash-dot (+ 2 3)))` in that case expression. This is a confusing aspect of `case` that is a leftover from our Scheme roots. You can avoid it by using `evcase` like Matthias suggested, but you might just consider using `match` instead.
