https://wiki.php.net/rfc/typed_class_constants#inheritance_and_variance As of php 8.3, class constants can have the same types as parameters (including union, intersection, and DNF types)

Start testing with php 8.3

-<ST_IN_SCRIPTING>"yield"{WHITESPACE}"from"[^a-zA-Z0-9_\x80-\xff] {
+<ST_IN_SCRIPTING>"yield"{WHITESPACE_OR_COMMENTS}"from"[^a-zA-Z0-9_\x80-\xff] {
        yyless(yyleng - 1);
        HANDLE_NEWLINES(yytext, yyleng);
        RETURN_TOKEN_WITH_IDENT(T_YIELD_FROM);

tests/cases/lexical/keyword5.php.tokens started failing in php 8.3 because php now lexes yield /*awesome*/ from as T_YIELD_FROM
