You shouldn't do that. If you have to count thinkers in a slot frequently something isn't right. Even natively the engine cannot do anything less than stepping through the entire list and incrementing a counter. This is a very costly operation because it involves several cache misses on the CPU.

Let's see if I fucked anything up, or if Graf doesn't want it in. (Or both)

How many active thinkers are in a particular stat.

Right now you can only do a while loop until it's all the way over which strikes me as inefficient when just trying to establish how many thinkers are in there -- especially if it's on ZScript's side. Probably much better to have it done on the source if anything, especially if this is done often.

What do you mean by "size of a stat"?

Simple. A static function that returns the size of a specified stat. If left empty or is some invalid number, defaults to maximum stat + 1 which means it gets the size combined of all stats.
