Row-major-aref is one more prove that common lisp standardization committee did such a great job. A feature that I needed and it was there thanks to John Thingstad for pointing out. Whenever proponents of minimalist languages whine about size of ANSI standard they should read about Simplicity .For the lazy here's my favourite part:
A lot of software developers are seduced by the old ‘80/20’ rule. It seems to make a lot of sense: 80% of the people use 20% of the features. So you convince yourself that you only need to implement 20% of the features, and you can still sell 80% as many copies.
Unfortunately, it's never the same 20%.
