Clojure is quite capable in interactive programming, through its REPL, so you must be talking about the lack of a condition system in the clojure core. But Common Lisp features like the condition system are already available in Clojure by just requiring (loading) the respective library. :) As an example, see https://github.com/clojureman/special . Nice thing about this repo is that it points to other options re. conditions with pros and cons of each one. Now that I think of it, you might also be referring to the fact that Common Lisp can load libraries through the REPL. Clojure can also do this through an alpha feature, add-lib, that you can already require in any project.

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

Yes, there are multiple libraries, for example: https://github.com/clojureman/special

Keep meaning to look at this, Clojure has some libraries for this I could use: https://github.com/clojureman/special#alternative-libraries

It turns out that it is, in fact, at least mostly possible to implement a condition type system in Clojure. See https://www.youtube.com/watch?v=zp0OEDcAro0 I did a little bit of googling for Clojure libraries that do this: https://github.com/zcaudate/ribol and https://github.com/clojureman/special I don't actually recommend any of these and haven't tried them. In particular I think using a non-standard library for your error handling, which is already probably relatively poorly tested, is probably a bad idea. I just wanted to point out that it's possible. I also think I remember something in a Rich Hickey talk (maybe "Clojure for Lisp Programmers"?) where someone in the audience asks about condition systems, and he responds that Clojure doesn't have one, but that it should be possible to build it.
