when parsing lots of files, working with the Token class has some method call overhead.

to reduce this to a minimum, we could turn this class into a pure value-object, meaning turn all properties readonly (which would require PHP8.1+) or even use a readonly class (which would require PHP8.2+) and turn all properties public:

<?php declare(strict_types = 1);
namespace TheSeer\Tokenizer;

readonly class Token {
    public function __construct(
      public int $line, 
      public string $name, 
      public string $value
     ) {}
}

that way accessing the data would get very fast

alternatively we could switch from token_get_all to PhpToken::tokenize() which internally uses a Token class similar to the above one.
