Hi @fabpot

Twig-CS-Fixer use his own Lexer because

• he needs to keep space/tabs
• he uses more token types

The implementation worked fine so far, but just got recently broke by the 3.21 release since I inspired my getOperatorRegex implementation by yours

I implemented a fix to follow your new implementation

Is there a way to write

$expressionParsers = ['='];
foreach ($this->env->getExpressionParsers() as $expressionParser) {
     $expressionParsers = array_merge($expressionParsers, [$expressionParser->getName()], $expressionParser->getAliases());
}

without an internal method ? Would it be OK to make getExpressionParsers part of the API ?

Thanks
