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 — step 2: typed pack indexing.
|
|
//
|
|
// `args[$i]` (with `$i` a comptime-known integer) inside a pack-fn
|
|
// body should resolve to the i-th call-site argument with its
|
|
// CONCRETE type, not the boxed `Any` that today's `[]Any` slice
|
|
// path yields. Without typed access, downstream operations on the
|
|
// element (field access, typed coercion, passing to a typed slot)
|
|
// either fail with "field 'X' not found on type 'Any'" or silently
|
|
// box/unbox through Any.
|
|
//
|
|
// This file pins today's failure: `args[0].x` on a struct-typed
|
|
// call arg trips "field 'x' not found on type 'Any'" because the
|
|
// AST-level type inference for `args[0]` returns Any.
|
|
//
|
|
// Next commit teaches `lowerIndexExpr` to detect a pack-name base
|
|
// with a comptime-int-literal index and substitute the i-th
|
|
// call-site arg's lowered value directly — propagating the call
|
|
// arg's real type through field access, typed assignments, and
|
|
// further indexing.
