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.

// Variadic heterogeneous type packs — generic `$R` with
|
|
// heterogeneous element pick. `foo(..$args) -> $R => args[2]`
|
|
// returns the THIRD arg's value; the ret type is inferred from
|
|
// the third arg's concrete type per call shape.
|
|
//
|
|
// foo(42, 3.2, "hello") → returns "hello" (string).
|
|
//
|
|
// Exercises:
|
|
// - generic `$R` inference for non-zeroth pack indices.
|
|
// - heterogeneous mixed-type call args binding into distinct
|
|
// types per position (i64, f64, string).
|
|
// - `pack_arg_types` type-only binding for `inferExprType`
|
|
// pre-mono-scope: without it, the synthesized-ident detour
|
|
// loses the type because the scope isn't set up yet during
|
|
// return-type inference.
