but there's a lot of code in a game codebase that isn't that
low level.
There's another way. Just don't worry about it being null, if
you're going to ensure it is initialized regardless. It'll seg
fault if it is dereferenced but not initialized.
Doesn't this seem to contradict the ".init is always a valid
state" ideal?
