I have misplaced Dawid's thread. There's an interesting thing about our current situation. I forgot to rationalize the package names on the collections when I last worked on them. So they are all .math.
This could be viewed as an opportunity. If HPPC or fastwhatever is a superior device, we could *add* it under org.apache.mahout.coll, leaving the colt stuff under math. Then we, over the long term, improve the naming, and avoid and abrupt incompatibility. Can someone suggest a way to get from Dawid's ascii graphics to a plan?
