Perhaps the disagreement stems from difference in experience. I sympathize with Sergey's confusion. When first coming to J a few months ago, I was confused by the exact same diagram. It only started making sense for me once the ideas of rank/splitting/reassembly and & vs @ composition had already clicked. So I feel like the diagram is a great illustration of the concepts but there is perhaps a need for some pedagogy that demonstrates the initial problem: What mechanical questions come up when trying to combine verbs? Which naturally leads to wanting the four composition primitives. Is there a wiki page that already addresses this kind of thing? I might try writing one up and sharing it on Jgeneral anyway, in the off chance it fills a need. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
