Honestly the safety is a far bigger drawcard to me than the performance. C(++)'s UB just scares me these days because it's often so subtle.

If you have to work with C++, I recommend using -fsanitize=undefined so you get runtime-errors when your program runs into undefined behavior. Very handy!

It's really useful, but it's dynamic. You need tests that actually trigger the UB to make it useful.

UB means unsigned byte in this context?

Undefined Behavior.

It adds a runtime sanitizer to detect some (but not all) UB.
