Move examples/*.sx and their expected/ snapshots into per-category subfolders (examples/<category>/...). Folder = leading filename token, with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus runner and LSP sweep now discover each category's expected/ dir, while issues/ stays flat. Example 1058's repo-root-relative companion import is made file-relative. Path strings embedded in 164 snapshots were regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.

// Pack-fn (or any comptime-param fn) with a block body containing
|
|
// an explicit `return X;` lowers to clean IR — the inline-return
|
|
// path stores into a dedicated result slot and branches to the
|
|
// shared `ret_done` block instead of emitting a `ret` inside the
|
|
// caller's basic block. Without that, LLVM's verifier rejected the
|
|
// IR with "Terminator found in the middle of a basic block".
|
|
//
|
|
// Surfaced by the variadic heterogeneous type packs feature (step
|
|
// 1 made `..$args` parseable, so the simplest pack-fn smoke test
|
|
// exercised the bug). The root cause is broader than packs: ANY
|
|
// comptime fn with `is_comptime` params, a non-void return, and a
|
|
// block body with `return X;` had the same crash. `format`/`print`
|
|
// use arrow form (`=> expr`) or `#insert`-only bodies, so the bug
|
|
// was invisible until pack-fn bodies surfaced it.
|
|
//
|
|
// Once fixed, calling foo() reaches the body's `return 42;`, the
|
|
// inliner stores 42 into a result slot, the caller loads it as the
|
|
// inline value, and main prints "42".
