Understanding what lisp-ers mean by 'repl-driven development' -- and why a python or node repl isn't it -- is really hard for people who don't get this, and haven't used it in practice.

(I use mostly Clojure) It's not even only about the syntax. The Python environment, as far as I understand (and please correct me if I'm wrong), does not support re-definitions very well. Some things can be re-defined, but some cannot. So that's a problem in itself which makes REPL-driven development not very useful in Python.

  Not sure why you'd say that. I redefine things often in Python.

    What about classes? Can you re-define those?
    - nerdponx 5y ago
      Yes, easily. Just re-execute the class definition code.

      Not only can you redefine classes, you can change the class an object belongs to. Just point `obj.__class__` at something else, or change `cls.__bases__` to reorganize the class's inheritance hierarchy.
