Load.program takes forms: it reads the import forms, resolves them with the one resolver it always had, and parses the file with the packages' macros in front of it. The refusal said this needed a second import resolver at the Form level. It did not notice that the file being compiled is parsed before Load runs too, so no shape of the feature could have left import resolution where it was. Names arrive qualified, as a defn's do. (mac/twice 4) is a call and (twice 4) is an unknown name. Stopped mid-task: dune test was never run and the acceptance wiring is unfinished. HANDOFF-macros.md has what is left.

;;;; The other half of the qualified-name rule: importing a package makes
|
|
;;;; nothing globally visible. [mac/twice] is the macro's name here and [twice]
|
|
;;;; is not a name at all, exactly as for a defn the package declares.
|
|
;;;;
|
|
;;;; It comes back as an unknown *function* rather than as an unknown macro,
|
|
;;;; and that is the honest answer: only [mac/twice] is in the expander's set,
|
|
;;;; so the walk never sees a head it recognises and the call reaches the
|
|
;;;; checker as what it looks like. Never built: the refusal is the test.
