On: Debugging Lisp code

[Estragon]

Seems a lot like the way I develop in python. Why is this remarkable?

[garply → Estragon]

I develop in both languages and I don't find them similar at all. If you modify a python module, for example, how do you easily re-import that module in your REPL? Python caches modules once imported and doesn't let you easily re-import a module that's been changed, right? And how do you modify a function and hot-swap it in while the rest of your code is still running?

[astine → Estragon]

It's remarkable for two reasons:

a) Because Lisp is where this programming style was invented.

b) Because it is being compared to C and Java-like systems where this kind of development is largely impossible.
