What you want is "infix":
2 <\ 3 1 4 1 5 9
┌───┬───┬───┬───┬───┐
│3 1│1 4│4 1│1 5│5 9│
└───┴───┴───┴───┴───┘
2 -/\ 3 1 4 1 5 9
2 _3 3 _4 _4

Lately, I find myself repeatedly comparing pairs in arrays.
I usually do something like:
d =: 3 : '-/"1 }. y ,. 0 , }: y'
d i. 5
1 1 1 1
It feels like I'm reinventing the wheel but I couldn't find a simpler way
(and more efficient for large arrays) to apply u over each pair of v.
Is there a better way?
