// Reserved-name MEMBER positions are EXEMPT from the reserved-type-name rule:
// a bare reserved spelling (`i2`, `u8`, `i1`, …) is legal as a struct FIELD
// name, a union TAG name, and a protocol METHOD-SIGNATURE name. These are
// unambiguous — the name sits in a member slot and is reached via `obj.name`
// (or dispatched by string), so it is never type-classified and never
// mislowers. The backtick form is optional there and resolves to the same
// member. Backtick access (`obj.`i2`) and bare access (`obj.i2`) both work.
//
// The exemption stops at member SIGNATURES: an `impl` method DEFINITION is a
// real function, so its name is a declaration site (like a free function) and a
// reserved spelling still needs the backtick (`` `i2 :: (self) ``) — bare would
// be type-classified and mislower (the issue-0076 protection). A bare reserved
// VALUE binding / declaration name still errors (see examples/1119, 1141, 1142).
// Regression (issue 0089 — attempt-7: pins the Agra-ruled member-name exemption).
