Checking something. I am seeing this:

component {
	private static function f(){
	}		

	private function g() {
		f() // 5.3.9.133: works fine; 5.3.7.47: errors with No matching function [F] found
	}
}

Is this because of https://luceeserver.atlassian.net/browse/LDEV-3334 ("static function cannot be used with dot notation") It's not explicit in the ticket that internal calls to static methods don't need to be called on the class, but I guess it follows.
