    - #### name

          public static java.lang.String name(int token)

      Returns a name for the token. If Rhino is compiled with certain hardcoded debugging flags in this file, it calls `#typeToName`; otherwise it returns a string whose value is the token number.

    - #### typeToName

          public static java.lang.String typeToName(int token)

      Always returns a human-readable string for the token name. For instance, `FINALLY` has the name "FINALLY".
      Parameters:
        `token` - the token code
      Returns:
        the actual name for the token code

    - #### keywordToName

          public static java.lang.String keywordToName(int token)

      Convert a keyword token to a name string for use with the `Context.FEATURE_RESERVED_KEYWORD_AS_IDENTIFIER` feature.
      Parameters:
        `token` - A token
      Returns:
        the corresponding name string

    - #### isValidToken

          public static boolean isValidToken(int code)

      Return true if the passed code is a valid Token constant.
      Parameters:
        `code` - a potential token code
      Returns:
        true if it's a known token
