Hi all,
from time to time, we might want to add some Rosetta snippets for our
favourite Smalltalk flavor.
I have added a Squeak entry for
https://rosettacode.org/wiki/Hamming_numbers#Smalltalk

This is related to the discussion having taken place here about
Generator(s), timesCollect: ...
I have used Xtreams for laziness capability.
It's not perfect, because the block read stream does not have absolute
positioning capability.
I could have used a Generator, if only it had the capability to skip a
batch of items...

The snippet is reasonably fast.

One of the pitfalls is the syntax for declaring classes and methods (bangs
gives a wrong idea of what Smalltalk coding is).
I guess that's one of the reasons motivating Pharo's Tonel format (like the
gnu format)
