Interactive development

I have semi-frequent occasion to work in Clojure, but Clojure lacks some features of Common Lisp that I consider important. The most important of these is that Common Lisp, like Smalltalk, but unlike most other languages, including Clojure, is designed from the ground up to support developing a program interactively while it runs. I want to see if I can have Clojure for those cases where it's the right tool, without losing the programming-as-teaching features of Common Lisp that I miss when working in other languages.

I know someone is probably going to object that Clojure, too, is designed to support interactive development; my answer is: no, it isn't. Not in the sense I'm talking about.

As an example of what I mean, consider the standard Common Lisp generic function UPDATE-INSTANCE-FOR-REDEFINED-CLASS. This function is part of a standard protocol in Common Lisp that enables your program to automatically update existing instances of previously-defined classes to properly confor

Awesome comment: https://www.reddit.com/r/programming/comments/65ct5j/a_pythonist_finds_a_new_home_at_clojure_land/dg9p8rk/

That's not an interpreter. A REPL is not the same as a Lisp interpreter. REPL means read eval print loop. EVAL can be implemented by a compiler or an interpreter. Common Lisp has both and mixed implementations with both compiler and interpreter.

A Lisp interpreter is executing Lisp code directly. Clojure does not have an Interpreter.

Clojure has no interpreter.
