// A `*self`-mutating streaming pattern with NON-reserved binding names
// (`hasher`, `ctx`) compiles and accumulates state correctly through BOTH
// call styles — explicit address-of `update(@h, ...)` and autoref
// `h.update(...)` — across multiple mutating calls. Proves the
// `.identifier`-only address-of paths in lowering are correct as-is, with no
// type-shaped-name special-case (companion to the issue-0076 rejection of
// type-named identifiers).
