as i see it, $first describes what is true of the implementation of passing
the object reference, but looking at the $this in the f
Very nice. And yes, too many brackets of various kinds.
Also $this doesn't really describe what it stores.
Maybe $first would be better?
And we can also optimize the performance by making the lexicals
constant (so the optimizer can hard-wire the method names into the
closure). That gives us:

Sure. Roll-you-own with:
module PAIR;
method car { return .key }
method cdr { return .value }

Incorrect - "cdr" can be anything at all, just like
Well, "car" and "cdr" don't really fit; the key and value of a pair can be any
type of object, unlike the Lisp case where the cdr is always a list
(while the car can be either a list or an atom). But you can always

Can I get a what what?
