// A reserved/builtin type name used as a PARAMETER name is rejected inside the
// two method-with-body forms that carry their params as bare name lists rather
// than `Param` nodes: a protocol default-body method (`u8`) and a sx-defined
// foreign-class (`#objc_class`) method (`i16`). The declaration-site diagnostic
// underlines the OFFENDING PARAMETER itself, not the enclosing `protocol` /
// `#objc_class` block — each method's `param_name_spans` is threaded from the
// parser so the caret lands on the parameter token.
//
// Regression (issue 0076, attempt-5 span precision). Expected: one error per
// offending parameter, each caret on the parameter name; exit 1.
