I'm blathering a lot here, sorry about that, but I found a case, now I just need to understand it:
A=: (|:++:) #:0 8 4 4 C=: (a:,];|:) #:0 6 11 1 D=: #:9 0 0 4 Now to see if I can understand what's happening here... I will try to refrain from posting my incomplete thoughts -- I'll try to come back with something that works.
