Invalid InvalidScalarArgument for uksort when used within a namespace

[azjezz]

code :

<?php

declare(strict_types=1);

namespace Psl\Arr;

/**
 * @psalm-template Tk of array-key
 * @psalm-template Tv
 *
 * @psalm-param array<Tk, Tv> $iterable
 * @psalm-param (callable(Tk, Tk): int) $comparator
 *
 * @psalm-return array<Tk, Tv>
 */
function sort_by_key(array $iterable, callable $comparator): array
{
    $result = $iterable;
    \uksort($result, $comparator);
    return $result;
}

error :

Psalm output (using commit 306ed07):

ERROR: InvalidScalarArgument - 19:22 - Argument 2 of uksort expects callable(array-key, array-key):int, callable(Tk:fn-psl\arr\sort_by_key as array-key, Tk:fn-psl\arr\sort_by_key as array-key):int provided

removing the namespace resolves the issue ( by definitely not a solution ) : https://psalm.dev/r/ee95831404

I found these snippets:

<?php

declare(strict_types=1);

namespace Psl\Arr;

function sort_by_key(array $iterable, callable $comparator): array
{
    $result = $iterable;
    \uksort($result, $comparator);
    return $result;
}
