Cool!

If that helps, I'm currently working on a "custom" type of collection used for sampling objects based on probabilities. Should be ready in a few days if anyone's interested. For lack of a better word, it's currently called "SamplingSet". To make a long story short, I'm using this to generate random data that mimics the statistical properties of those objects in the real world. For example, if I'm generating last names for say an instance of class Person for Russia, chances are you should very rarely get any "St-Jean" as opposed to "Ivanov" so this collection samples those last names accordingly based on their probabilities. So all that SamplingSet does is return a random object that respects the statistical probability of such an occurrence.

I'm working on a few optimizations as I'm having to deal with sets of a few million items and right now, the 4M mark seems to be hard to break without paying a high price.  But I should be done withing a week or so.

Hi!

In Moose there is a project call "Hashtable". The goal of this project
is to provide faster collections when they have a big number of
elements.

I think this is something that can be useful for more than just Moose
so I extracted it to pharo-contributions so that we can use it and
improve it more.

Have a nice day.
