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.
