Yeah, I'm all for fast iteration, was just musing aloud if there's some extra benefits to using Rust.

For instance your crash protection catches execution failures, but what about data failures? If you've got a write-past on an object nothing is going to be keeping you from destroying the rest of the world(unless all allocations in a hot-reload scenario are constrained to separate pages that you can protect?).

Seems like a lot if things you're trying to avoid by catching crashes are built-in to Rust.
