Mmm, yummy. I do have a question though (and apologies if I've merely missed the answer). We've got two productive operation-formation rules: one saying "add a final = to operate-and-assign", and the other saying "wrap in [] to vectorise". But no-one's said which order they apply in. That is, which of these should I type: @x [+]= @y; @x [+=] @y; Of course, the rule ordering didn't matter with the "add a leading ^ to hype" rule. I think I prefer the first one, by the way -- it strikes me as more obviously a vector add. -- Aaron Crane * GBdirect Ltd. http://training.gbdirect.co.uk/courses/perl/
