The trio the author decided on 2026-09-20 is now all built: def is CL's
defparameter — its initialiser runs on every daemon re-run, unguarded, so
an edited initialiser repaints the same storage on C-c C-c plus re-run —
defonce (Clojure's name for CL's defvar, per the author) initialises once
behind the .init~once. flag, and defconst stays the image.
One parse arm reads both forms; the difference is Ast.reinit, carried to
Tast.global's grerun. Emit.startup_plan gives a def no guard flag, and
Check.check_global lifts every def initialiser — zero and literal
included — into global/<n>, so the host's startup reaches it through the
function cell and a re-evaluated def swaps it (Session's def_inits;
Emit.redefinition declares the cell for a non-sibling target). The old
defvar spelling is refused with the rename and both compiling spellings,
and every program, test, doc and editor list is swept — except sand.flan,
the author's live WIP, whose seven defvar lines are flagged in FIX.org
and keep its three dependent tests red on this branch.
The author's exception to the foreign-spelling list: int is i32 and float
is f32, and nothing else on that list moves.
Spelled in Types.ikind_of_name and Types.fkind_of_name rather than as two
prelude defaliases, because Check.is_cast asks those two functions and never
the alias table — a prelude alias would have left (int x) with no reading
while (i32 x) had one. Both names join primitive_names for the same reason
one layer down: that list is what decides (vec-new int) and the three-element
(defvar x int).
Nothing reverses: ikind_name still says i32, so every message, signature,
inspector line and DWARF name shows the machine type whichever spelling was
written.
A defalias restating the builtin is the no-op it says it is; one pointing the
name anywhere else is refused, since the alias table is never consulted and
the declaration would otherwise mean i32 in silence.
