This is a binary view of development-verses-production. I appreciate languages that treat this as a continuum and let me make my own trade-offs.

Common Lisp, Smalltalk, and Erlang all treat the process as running indefinitely. This gives those languages a certain something special.

I was hoping to find the same thing in Julia. It's not there. It seems like a significant missed opportunity to me. These dismissive comments make it sound like you guys might not know what you are missing.

We legally cannot do things like say live code change the production system underlying the analysis of ongoing clinical trials without going through the whole software development lifecycle required by the FDA (I.e. the Pumas example again), so even if it did exist all a lot of the production systems we're running legally couldn't use it. But also, you can do it with Revise+RuntimeGeneratedFunctions, obviously that solves the mentioned world age issue so I don't see what the fuss is all about? I don't see how offering a solution is dismissive?

but you can adhere to legal requirements and go through all the code and test reviews and still have live update capability. i don't see why they are exclusive. moreover, there are scenarios where taking the system off-line for an update would cause a critical failure

Okay, so then use RuntimeGeneratedFunctions+Revise. Done. Julia can do it, but having a setup so that people can do instant review of changes on the live production system is still a little bizarre and I wouldn't do it even though we could.
