defrecord/deftype expands to (do (def R (make-deftype-ctor ...)) (def ->R R) ...), so the ->R alias references R within one compiled unit. Under direct-link a var ref embeds the cell's root as a compile-time constant, but on a redefine R's old root is still in place when that unit compiles — the (def R new) sibling hasn't run yet — so ->R sealed to the stale pre-redef ctor. (defrecord R [x a]) (defrecord R [a x]) (:a (->R 10 20)) read the old [x a] layout and returned 20. Track the vars a unit (re)defines and force their later in-unit references to the live indirect deref. The cell is registered only after its own init is emitted, so a recursive self-reference inside the init still direct-links (it runs after the def completes); only sibling references after the def go indirect. |
