(defmacro do-grid [[r rows c cols] & body] ...) — positional names, a [ ] pattern wherever an argument is a vector, and & for the tail. The reading of the list lives in Expand, below both sides that need it: Parse turns it into the bindings a macro body opens with, and Macro checks a call against the same reading before expanding it, so arity and shape are refused with the call's own location rather than with the Loc.from_macro stamp every node of an expansion carries. The breaking half: [args] used to bind the whole argument list and now binds the first argument. The whole list is [& args], and every defmacro in the tree — prelude, vendor, tests, the elisp fixtures — was migrated to it. One grammar, not a legacy mode.

;;;; A ring of macros, in a package. Neither body can be compiled first, so

;;;; there is no order to compile them in -- and an import's macros go through
|
|
;;;; the same rounds as the file's own, so the refusal has to fire here too.

;;;; Nothing in this package calls them, so the ring is found by the importer.
