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 — `..$args` — impl matching

// today's concrete-only impl-matching behaviour: a user-declared

// `impl Into(Block) for Closure(..$args) -> $R` does NOT match

// any concrete closure source type. The xx cast site hits the
|
|
// existing "no `Into(Block) for <src>` impl" diagnostic even
|

// though the pack impl is reachable.

// Next commit (1d.B) teaches `tryUserConversion` /
|

// `registerParamImpl` to walk a second `param_impl_pack_map`
|
|
// when the concrete-key miss happens. Pack impls bind their

// `$args` and `$R` to the concrete source closure's tail types
|
|
// and return; monomorphisation proceeds against those bindings.

// `Closure(bool) -> void`) and not covered by 96-block-multi-arg's
|
