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 4 final slice (4A
|
|
// bare): `$args` referenced bare (without `[...]` indexing) in
|
|
// expression position should evaluate to a comptime `[]Type`
|
|
// slice value — the whole pack passed through as data so
|
|
// builder fns can walk it.
|
|
//
|
|
// Use case (eventual): step 5's generic Into(Block) impl body
|
|
// convert :: (self: Closure(..$args) -> $R) -> Block {
|
|
// #insert build_block_convert($args, $R);
|
|
// }
|
|
// where `build_block_convert(args: []Type, ret: Type) -> string`
|
|
// is a regular sx fn the interp executes — it walks `args` to
|
|
// emit a trampoline fn matching the per-mono signature.
|
|
//
|
|
// Today the parser-arm I wrote for `$<ident>[<int>]` (commit
|
|
// fd03b58, M5.A.next.4.3) REQUIRES the `[` after the pack
|
|
// name; bare `$args` hits a focused diagnostic. This file
|
|
// pins that rejection. Next commit makes the `[` optional —
|
|
// no `[` yields a `comptime_pack_ref` AST node which lowering
|
|
// converts to a `[N x Type]` aggregate of `const_type` values.
