Right, the same claims are made by the K people, it seems. You can 
highly optimize vector operations.

One of the applications of K appears to be a database system that is
way more compact and way faster than traditional databases. In fact,
it sounds quite a bit like metakit, in that it's column based. They give
this as an example of the power of K. 

K does looks like line noise, though. Very much so. :) And I've found that
Python code is only 3 times as long or so, while being more readable.
(and a lot slower) This from a very limited experiment!
