<?php

use CuyZ\Valinor\MapperBuilder;

require 'vendor/autoload.php';

final class a {

    /**
     * @param array{a: int}|array<never, never> $a
     */
    public function __construct(
        public readonly array $a,
    ) {
    }
}

(new MapperBuilder)->mapper()->map(a::class, []);

Throws:

PHP Fatal error:  Uncaught CuyZ\Valinor\Mapper\TypeTreeMapperError: Could not map type `a`. An error occurred at path *root*: Cannot be empty and must be filled with a value matching type `array{a: int}|array<never, never>`. in /home/daniil/repos/valinor/src/Mapper/TypeTreeMapper.php:29
