PHP 8.4 is not officially supported

I was just crawling thru github for this particular php compat problem.

Its not important for me to make this repo PHP 8.4 compatible

I think this would be better filled by using ReflectionFunction::isAnonymous in 8.2 and up

Not if we gate it with a PHP_VERSION_ID check. This change makes me uneasy. This check was sketchy enough to begin with.
