i wonder if exit is considered infallible. afaik we have decided sometime before that we add only infallibles to builtins, right?

I think that it’s as infailable as echo so we can assume it’s infailable

tbh i dont think that even echo is infallible. there are some conditions where there is no fd 1, right?

@b1ek Yeah. But then can we even run anything bash related?
