I found these snippets:

https://psalm.dev/r/240410c30c

<?php

class Foo
{
    /** @var array<string, class-string<self>> */
    private static $classes;
    
    /**
     * @param class-string<self> $class
     */
    public static function register(string $key, string $class): void
    {
        self::$classes[$key] = $class;
    }
}

Psalm output (using commit 8926f1d):

ERROR: InvalidPropertyAssignmentValue - 13:9 - Foo::$classes with declared type 'array<string, class-string<self>>' cannot be assigned type 'non-empty-array<string, class-string<Foo>|class-string<self>>'
