The expression $previous of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

            &&
            $this->lexer->token['type'] !== EmailLexer::GENERIC;
    }
