Hey guys!
Umm, I wanted to know what exactly does these lines mean and what are they used for.
Would somebody be so kind and fully explain it to me? (and yes, i have read the foreach post)

Код:

new Iterator:Some<10>; // I do not know what does the '<10>' mean and why do I need it there.
Iter_Add(Some, 5);
Iter_Add(Some, 9);
