As the cousin comment stated, we use sources. Even with this condition/restarts/debugger: fix the error in the source and recompile it, not in the REPL.

And we have the right to restart the image. For example, I run the tests from the terminal, hence from scratch, from time to time, typically before pushing my commits. I have a CI that tests and builds the program. I deploy a static build. We don't use images coming from development here. However, I can connect to a running image in prod and tweak settings if I want, or just look around[]. I could very easily change the code, but I'll do that in my sources and do a clean deploy. Or not. I too heard about people who mold a running image for years, their sources totally out of sync O_o

[]: there's a trading startup that posts screenshots of their Sly REPL from prod, that's where they ask their system for data. They didn't have to setup another complex layer just to see data from prod.
