I actually just dusted off my old Clojure stuff to see if it was a "solved problem", and it isn't.

I grant that it might be described thus if I started out with that stack, but trying to retrofit an older code base with it is, I have found, next to impossible. You have to code around the myriad gotchas as you go or you're never going to identify all those landmines going back over it after the fact. The errors and bad behaviors are too difficult to identify, even for the `native-image` tooling.
