C-c C-m. One step on the bare key, the fixpoint under C-u: a macro may quasiquote a call to another macro, and Loc.from_macro is outermost-wins, so by the time a full expansion settles the intermediate name is gone. One step is the only thing that can say which macro produced what. The expansion runs against the macros the *session* holds -- the prelude's, its imports', and every defmacro evaluated since it started -- and writes nothing back: a defmacro handed to C-c C-m does not join the session by having been looked at. Both non-termination refusals stay refusals, and only where they are needed. One step makes one call and does not look at the answer, so (s/spin) one- stepped answers with itself; all the way hits the fuel and names the macro, inside Dev.serve's guard, so the daemon replies rather than hanging. Macro's module handling is a Fun.protect now -- a build that raised was a process about to exit, and the daemon is not that process. No printer for a Form existed. Form.to_string is an error-message renderer and is what Macro.key digests, so it is untouched; Form.to_source round-trips floats, strings and bytes through the reader, and Form.pretty decides where the line breaks go and leaves the columns to flan-mode. The answer is a read-only flan-mode buffer shaped like the disassembly one, with cnr's idea in it: m expands the form at point one more step in place. Three inherited keys refuse by name -- an expansion is in no file. The text is sent padded onto its own line and its own column, unlike C-x C-e, so the refusal lands on the call and not at the start of its line.
