- objc.sx, objc_block.sx (from std/) + sdl3/opengl/raylib/stb/stb_truetype/ wasm vendor bindings (from modules/ root) -> modules/ffi/ - std/uikit.sx deleted: platform/uikit.sx already declares UIApplicationMain and imports objc; '#framework "UIKit"' cannot live in a file imported on macOS targets (unconditional link directive, UIKit is iOS-only), so the three iOS-only examples carry the 3-line glue inline. 1607/1608/1616 also un-rotted (dead ns_string -> 'xx "..."' Into conversions, callconv(.c) msgSend fn-ptrs) — all three build for ios-sim/ios again. - math/math.sx -> math/scalar.sx; one spelling '#import "modules/math"' everywhere (4 pinned IR snapshots regenerated: dir import adds Vec2/Mat4 to the type tables). - compiler.sx -> build.sx (imports, CLAUDE.md bundling table, specs.md). - testpkg/ + test_c.sx -> tests/fixtures/ (resolve CWD-relative from repo root, same as vendors/). - library-internal imports use full modules/... paths (std.sx tail, platform/bundle.sx, fixtures).

// `xx closure : Block` for an arbitrary closure signature.

// The stdlib (modules/ffi/objc_block.sx) declares hand-rolled
|
|
// `Into(Block) for Closure() -> void` and `Closure(bool) -> void`
|
|
// impls — the two most common Apple block shapes. Other signatures
|
|
// need a per-shape `__block_invoke_<sig>` trampoline + `Into(Block)`
|
|
// impl declared somewhere reachable (stdlib if shared, in-file if
|
|
// app-specific).
|
|
//
|
|
// This test exercises the user-declared variant: signature
|
|
// `Closure(s32, *void) -> void` (a two-arg block — not in stdlib).
|
|
// If the impl is missing, the compiler emits a focused diagnostic
|
|
// pointing at modules/ffi/objc_block.sx as the template.
