The Python repl isn't really anything like a Lisp is it? Like you can run the interpreter interactively, but every language has that. That's not a Lisp REPL where you can edit and save code while it's running and then just commit it. Unless I am missing some awesome features of the python repl :)

No, not "every language" has a REPL. Most languages I have worked with don't. It's true that python doesn't have hot-reloading, and that its built-in REPL is less powerful than Emacs. But not every lisp has all of that power, either. And personally, I find the Jupyter notebook to offer all that I'd ever want from Emacs, with a better interface.

But REPL stands for "read, eval, print loop." My kitchen knife doesn't fail to be a knife because it's missing the corkscrew, flashlight and screwdrivers of a Swiss army knife.

I meant every scripting language.
