It bugs me to no end that Rust _almost_ got conditions and restarts. Apart from proper macros, conditions and restarts are one of the few things that CL has that no other language has mimicked. Sure, I have seen it faked in scheme with call/cc, but that will never be a proper, fast solution.

I think guile at least got prompt and abort functionality which makes it mostly doable? Also, bizarrely, http://p3rl.org/Worlogog::Incident http://p3rl.org/Worlogog::Incident exists.

  Not only doable, but rather efficient. Delimited continuations are superior to undelimited ones in every way.

Where can I read about conditions and restarts?

  Peter Seibel talks about it in Practical Common Lisp and in the talk he had at Google about the book: https://youtu.be/VeAdryYZ7ak https://youtu.be/VeAdryYZ7ak The book is available online I think.

    Thanks! That is definitely an interesting concept.
