Rewrite specs.md tuple/failable/pack/UFCS/grammar sections to the new syntax, update readme.md, and refresh stale tuple references in example header comments. Also fixes two pre-existing doc inaccuracies surfaced in review: drop the value-discarding `;` in the tuple-return examples, and correct the §13 function-type grammar production (optional param list + optional trailing `!` channel). Optional semantics unchanged. current/CHECKPOINT-LANG.md logs the cutover.

// E6b-R — route-all: the NEW use surfaces a same-name type reaches now funnel
|
|
// through the source-aware engine, so an ambiguous bare name poisons LOUDLY at
|
|
// each of them instead of silently picking a global `findByName` last-wins author.
|
|
// `main` flat-imports two same-name `Box` struct authors and authors none itself,
|
|
// so every bare `Box` below is a genuine collision. `Box` is the kind-agnostic
|
|
// canary (the bare-leaf forms — annotations / size_of / match / `!Named` — are
|
|
// already locked per kind by 0755/0795/0797/0811); these cells exercise the
|
|
// surfaces E6b-R added:
|
|
//
|
|
// - wrapper-alias element `BoxPtr :: *Box` (engine wrapper aliasing)
|
|
// - union body-builder child `WrapU :: union { b: Box }` (C1, registerUnionDecl)
|
|
// - enum body-builder child `WrapE :: enum { V: Box }` (C1, registerEnumDecl)
|
|
// - tuple-type element `size_of(Tuple(Box, i32))` (O1/K5)
|
|
// - inline-anonymous body child `x : union { b: Box }` (inline-anon engine arm)
|
|
//
|
|
// Fail-before (pre-E6b-R): each of these resolved `Box` through the stateless
|
|
// `type_bridge.resolveAstType` global last-wins, silently binding one arbitrary
|
|
// author with NO diagnostic. Pass-after: every surface emits the LOUD
|
|
// "type 'Box' is ambiguous" and the build exits 1.
