Incorrect InvalidLiteralArgument when usage dirname()

[vjik]

function test(): bool {
    $path = dirname(__DIR__, 4);
    return strlen($path) > 6 && str_contains($path, 'vendor');
}

For no duplicate dirname(__DIR__, 4) I use variable $path, but psalm throw InvalidLiteralArgument. Seems, it's incorrect.

I found these snippets:

<?php

function test(): bool {
    $path = dirname(__DIR__, 4);
    return strlen($path) > 6 && str_contains($path, 'vendor');
}

Psalm output (using commit aec0edc):

ERROR: InvalidLiteralArgument - 5:46 - Argument 1 of str_contains expects a non-literal value, but '/var/www' provided

$d = __DIR__;
echo str_contains($d, "psalm");
