To note is that, while it's easy to remember the word for sum/product/any/all/raze/max/min, you have to know that there's a word for it in the first place. In contrast, in APL, once you know about reduce, there's just one way any of those could be written, and it's obvious. And after you learn about scan (cumulative reduction), you also know the cumulative version for all of those!
