This one is fine:

Psalm misses this one:
https://psalm.dev/r/c5d8cd84d8

I found these snippets:

<?php

class Foo {
    public static function bar(): void {}
}

$callable = 'Foo::bar';
$callable();

Psalm output (using commit 21e5678):

No issues!

<?php

class Foo {
    public static function bar(): void {}
}

$callable = '\Foo::bar';
$callable();

Psalm output (using commit 21e5678):

INFO: UnusedClass - 3:7 - Class Foo is never used
