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 source-construction
|
|
// path: `$args[$i]` in expression position yields a comptime Type
|
|
// VALUE (`Value.type_tag(TypeId)` in the interp). Lets builders +
|
|
// pack-fn bodies dispatch on the i-th pack type at compile time.
|
|
//
|
|
// Two usage shapes covered here:
|
|
//
|
|
// 1. `type_name($args[0])` — the value-form Type goes through the
|
|
// reflection intrinsic, picking up the per-mono concrete type.
|
|
//
|
|
// 2. `inline if type_eq($args[0], s64) { ... }` — compile-time
|
|
// branch over the pack element's type. The fold via
|
|
// `tryConstBoolCondition` reads $args[0] via `resolveTypeArg`,
|
|
// which the step-4 work taught to walk `pack_arg_types`.
|
|
//
|
|
// Lowering: `$args[$i]` in expression position emits a
|
|
// `const_type(arg_types[i])` IR op. The interp materialises a
|
|
// `Value.type_tag(TypeId)`. LLVM emit bails (Type is comptime-only).
