[Pharo-project] is there an easy way to know the SmallInteger instances?

Mariano,

I see your point, but given the immediate object encoding tricks I'm not sure it's possible.  Would the class methods #minVal and #maxVal be of any use to you?

Subject: [Pharo-project] is there an easy way to know the SmallInteger  instances?

If I do SmallInteger alIInstances I get an empty array, and of course, with SmallInteger instanceCount I get zero.

Now, I can understand that from the VM point of view, but for the final user, this should be polymorphic. For example, for instanceCount, I would like to know all the "variable slots" that has a 1 in the last bit.
Is this already possible?   if true, which message?   if not, should I hack in the vm and code a primitive that does this?

And the same for allInstances, if I can inspect  5, I should be also to inspect  SmallInteger allInstances, and SmallInteger allInstances first, etc....

thanks

Mariano
