  // in dot notation or captured inside brackets — may contain any character
  // except `.`, `[` and `]`, so a key like `user-name` or `user name` is kept
  // literal instead of being split (#5402). `.`, `[` and `]` keep their existing
  // meaning, e.g. `foo[bar.baz]` -> ['foo', 'bar', 'baz'] and `[]` is an array push.
  // Excluding `[` from the bracket group also makes the match fail fast at the
  // next `[`, so a malformed name cannot rescan to the end of the string from
  // every unmatched `[` — parsing stays linear in the length of the name.
