Since this won’t work with null, probably change this to take a reference at some point.

Would like to remove the extra set of parentheses here, too.

Could we have used reference types here instead of pointer types? I’m not thrilled with functions that use "pointers that are known to never be null". We’d have to add some * at the various call sites, but I think that’s better than having the dereferencing hidden inside the functions.
