well, sorry for forgetting to actually answer your question. :-P
So, these SmallIntegers are always created implicitly when performing
computations. No allocation is associated with creating one, it's
purely arithmetics. So, it doesn't make sense to send #new to
SmallInteger - if you need one, say, 42, just create it by typing 42
in a workspace and inspecting it.
Another neat feature of this representation is, by the way, that you
cannot possibly have two different instances of SmallInteger
representing the same number. SmallInteger equality is simply checked
by comparing the pointers. Very cheap.
