Hey all, I made an adverb ('xy') that lets trains refer to their arguments explicitly.
Example: f =: (Y * X + Y)xy 1 2 f 3 4 12 24 X and Y behave like [ and ], but reference the arguments of the whole train: 0 1 (2: X 3:)xy 4 5 0 1 0 1 (2: Y 3:)xy 4 5 4 5 I have no use for it yet, but it was fun to make. :) https://github.com/tangentstorm/tangentlabs/blob/master/j/tacitxy.ijs ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
