CF allows you to declare into existence arrays that are only of first normal form (from a data integrity perspective). What this means is that, just as in the example in the article, a programmer can create a 2-D array that has in essence 3 columns for one row and two for another. That's a huge no-no in every other language that I am aware of that allows you to create arrays, and for good reason. Arrays should follow certain rules to maintain data reference integrity. I am seeing here that that is not guaranteed. Granted, I am new to CF and overall I do like what I am seeing of it. Just this piece of things strikes me as being.... very unorthodox.
