The canonical sx block-body lambda is `(params) { stmts }` (and
`(params) -> Ret { stmts }`); the arrow form `=>` is for EXPRESSION bodies
(`(params) => expr`). The arrow-block hybrid `(params) => { .. }` was being
used in 33 files — convert all of them by dropping the `=>`. The two forms are
exactly equivalent (verified: identical IR and identical runtime values — the
block tail is the value with or without a `-> Ret`), so this is a pure source
cleanup: no `.ir` churn, and the only snapshot change is 0923's diagnostic
COLUMN (a negative narrowing test whose error span shifted by the removed `=> `).
Arrow EXPRESSION bodies (`=> expr`, `=> .{..}`, `=> [..]`) and `=>` inside
comments/strings were left untouched. Migrated across examples/concurrency,
examples/{closures,ffi-objc,generics,optionals,types}, issues/, and the stdlib
(io.sx, sched.sx). Suite 855/0.

// ffi-objc-arc-01 — M4.A smoke test for NSObject + autoreleasepool.
|
|
//
|
|
// Exercises:
|
|
// 1. NSObject is declared in std/objc.sx and reachable from user code.
|
|
// `obj.retain()` / `obj.release()` dispatch via the M2.3 #extends-aware
|
|
// method chain. Pattern: `defer obj.release();` as the canonical
|
|
// sx idiom for owned Obj-C handles.
|
|
// 2. `autoreleasepool(body)` stdlib helper wraps `body` in a
|
|
// push/defer-pop pair so Foundation factory returns drain at block
|
|
// end.
|
|
//
|
|
// macOS-only — libobjc + NSObject must be available at runtime.
|

|
// push/pop pair executes. We don't have a side-effect to observe
|
|
// (NSObject.new returns a +1 retained, NOT autoreleased), so this

// is a smoke test of the helper's shape, not the runtime
