// Backtick raw-identifier escape: a leading backtick makes the following
// identifier RAW — its text excludes the backtick and it is never the
// reserved/builtin keyword, so a reserved type-name spelling (`s2`, `u8`, …)
// can be used as an ordinary identifier. Exercised in every VALUE position:
// global, local, param, struct field + member access, function name + call,
// and a later reference. (A raw identifier in TYPE position references a
// backtick-declared type instead — see examples/0154.) A *bare* `s2` is still
// the reserved type name (see examples/1119), so the escape is the only way to
// spell these as values.
// Regression (issue 0089).
