I'm not saying that rust has no such issues, I'm saying that a huge
majority of the stupid things we do in C just don't happen in the same
code implemented in rust (i.e. memory leaks, error path cleanups, return
value checking, etc.)

So sure, let's make different types of errors in the future, not
continue to make the same ones we should have learned from already
please :)
