Question: consistency with what?

It seems to me that most accessors are in the form `<name>$<lowercase-accessor-kind>` - e.g. `foo$get`.

Then we have upper-case names for constants (e.g. layouts).

I can see us going either way here - e.g. treating the `addressof` as an accessor, or as a 'constant'. I slightly
prefer the former, as it corresponds to the `&` operator in C. E.g.

x.y // getter
x.y = ... // setter
&(x.y) // addressof
