I can't tell from the video if the hot code reloading is meant for production workflows or dev only workflows. For example being able to use HCR to update a long-lived TCP server (like a video streaming server) without disconnecting clients.

It seems like it forces pointers for everything which, which seems to me will break a lot of optimizations (like inlining)

Edit: I guess production use is limited anyway since you can't add, modify, or remove types with HCR yet.

Edit2: I just saw in the video they said it's 2x times slower, so definitely can't be used for a lot of workflows in production. Still useful though.
