This is not true in general. For example `static::class` is not =
resolvable at compile-time.

(In fact, many years ago, when I played with that new feature, I almost =
filed a bug report saying that `static::class` is not supposed to work, =
since it is not resolvable at compile-time.)

(Additionally, since PHP 8, it is also possible to write =
`$object::class`, see: =
https://wiki.php.net/rfc/class_name_literal_on_object =
<https://wiki.php.net/rfc/class_name_literal_on_object>. But =
`static::class` worked since 5.5.)
