Dylan! (Which is commonly called a Lisp dialect due to its internal structure, even though it lacks homoiconicity.) See https://opendylan.org/documentation/intro-dylan/conditions.h... There are implementations of condition systems as libraries, too. Copying links from my book: * Python: https://github.com/svetlyak40wt/python-cl-conditions * Clojure: https://github.com/clojureman/special * Ruby: https://github.com/michaeljbishop/mulligan * Perl: https://metacpan.org/release/Worlogog-Incident, https://metacpan.org/release/Worlogog-Restart

This book looks great! I tried to implement this in Ruby with a gem about 6 years ago and got really close. If anyone wants to know more about this, but is more fluent in Ruby, you might find this a good jumping-off point. There’s a good explanation in the README. https://github.com/michaeljbishop/mulligan Why did it not work in the end? Because even though I was able to implement an error-recovery mechanism that wouldn’t pop the stack, it still triggered all the `ensure` statements that were up the stack. It was still a valuable exercise. I'd welcome this addition in any exception-based language.
