Rename all example tests/companions to the XXXX-category-test-name scheme (per-category 100-blocks: basic 0010, types 0100, ... errors 1000, diagnostics 1100, ffi 1200, ffi-objc 1300, ffi-jni 1400, vectors 1500, platform 1600). Companions and dir/C fixtures move in lockstep with their parent test; #import/#source/#include paths rewritten to match. Expected output now lives in examples/expected/ (a sibling dir of the tests) split into three streams per the new convention: <name>.exit / <name>.stdout / <name>.stderr (+ optional <name>.ir) run_examples.sh rewritten: scans examples/ and issues/ for an expected/<name>.exit marker, captures stdout and stderr separately (no more 2>&1), compares each stream + exit + optional IR snapshot. Behavior validated unchanged: every renamed test reproduces its prior merged output + exit (diffs limited to file paths/basenames embedded in diagnostics + traces, which correctly reflect the new names). Suite: 292 passed, 0 failed. 50-smoke.sx split + issue relocation + docs follow in subsequent commits.

// 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.
