History
Joseph Ferano b9f5b5c44c A promise the compiler cannot check gets its own refusal, and a session expands its buffer's macros 
Two loose ends from NEXT.md.

slice-from-ptr's run-time refusal borrowed @flan_slice_error and reported a
range and a length the caller never wrote. It has flan_slice_promise_error
now: signals BoundsError, walks the handlers, offers the break loop, falls
through to a message and a status like the two beside it. The sentence names
what was promised and what was passed, and a second line says what is not
checked. The condition fields stay (0, n, 0) — the violated condition as a
range, and not (0, n, n), which reads as in bounds.

And a session now holds the buffer's own defmacros: seeded in Session.create
from the same read that produced decls, and added by Session.eval so a
defmacro typed at the editor joins the set the way a defn does. Not a re-read
of the file, which would put unsaved-versus-saved skew inside expansion. The
commit stays below the checker. Macro.program dedupes the ambient set against
the forms being parsed, left-wins, because unqualified names can now collide.
