lowerComptimeCall stamped the caller's source onto fixed comptime `$`-params
so their substituted bare names resolve in the caller's visibility context,
but the variadic comptime pack branch (`..$args`) recorded the pack-arg slice
without stamping. Those nodes are later re-lowered via packArgNodeAt under the
defining-module pin, so a caller-owned helper in a formatted-arg position
(`std.print("{}", caller_fn())`) was checked against the metaprogram's module
and rejected as "not visible". Stamp every pack-arg node with the caller source,
mirroring the fixed-param treatment — completing Problem 1 for pack args.
Regression: examples/0739-modules-comptime-pack-arg-caller-context.sx
(two caller-owned s64 helpers in std.print pack positions; fail-before both
"not visible", pass-after prints "42 7"). No exemption flag, no silent default.

// Caller-owned helpers passed as VARIADIC comptime-pack args (`..$args`) to a
|
|
// NAMESPACED imported metaprogram resolve in the CALLER's visibility context —
|
|
// not the metaprogram's defining module (regression, issue 0106 follow-up).
|
|
//
|
|
// `std.print :: ($fmt: string, ..$args)` is authored in `std.sx`; the pack args
|
|
// `caller_num()` / `caller_two()` are authored HERE in the caller. The body's
|
|
// typed `args[i]` substitution (via packArgNodeAt) lowers each pack arg under
|
|
// the metaprogram's defining-module pin, so without stamping the pack-arg nodes
|
|
// with the caller's source, the bare names `caller_num` / `caller_two` were
|
|
// wrongly checked against `std.sx` and rejected as "not visible". The fixed
|
|
// comptime param (`$fmt`) already got this treatment; this extends it to every
|
|
// node in the variadic pack. The metaprogram's OWN code (build_format / out)
|
|
// still resolves in `std.sx`, so the defining-context pin stays intact.
|
|
//
|
|
// Two pack positions lock that EVERY pack arg is stamped, not just the first.
|
|
// s64 values only — accepted by print at runtime today (no 0107/0108 coupling).
