I've tried to use Data.Ix with Data.Vector for image manipulations and I confused column with row-major indexing.
I expected than Data.Ix.index ((0,0),(3,3)) (1,0) == 1 while it is actually equal to 4.
Documentation for Data.Ix should explicitly state that it is row-major indexing and function Data.Ix.index might be accompanied by example like: index ((0,0),(3,3)) (1,0) == 4 which should be obvious.
