Parentheses in types are not supported

[danog]

In the following example, a mapper error is only thrown when validating b, not when validating a.
Note that parentheses are supported by both psalm and phpstan, and are actually often generated when using phpcs in fix mode, which makes use of phpstan's docblock parser and printer.

<?php

use CuyZ\Valinor\MapperBuilder;

require 'vendor/autoload.php';

final class a {

    /**
     * @param (0|1) $a
     */
    public function __construct(
        public readonly int $a,
    ) {
    }
}

final class b {

    /**
     * @param 0|1 $a
     */
    public function __construct(
        public readonly int $a,
    ) {
    }
}


(new MapperBuilder)->mapper()->map(a::class, 2);
(new MapperBuilder)->mapper()->map(b::class, 2);
