Ok, I can see your point of view. That said, the DoJ is not the implementation. That said, the GPL'd version of J has an implementation that uses inner product so it's true that intermediate results would be different. That said, the equivalent primitive in earlier versions of APL did use Horner's rule (or at least: that is what Ken Iverson told me).
