Is there a way to count the childrens of a class i.e.

I want to do something like this.. Explantion :

$count = class(5).childrensCount;
$rate = (0.7/$count);

htb(rate 1Mbps, ceil 1Mbps) {
	class(5, rate 0.7Mbps, ceil 1Mbps) {
		class(rate $rate Mbps, ceil 0.6Mbps) {};
		class(rate $rate Mbps, ceil 0.6Mbps) {};
		class(rate $rate Mbps, ceil 0.5Mbps) {};
		..............................
	}
	class(rate 0.3Mbps, ceil 1Mbps) {
		...similar thing
	}
}


So that rates scalles according to the count of the children...
