Instead of when1,then1,when2,then2,...[,case][,else] sort them as [case,]when1,when2,...,then1,then2,...[,else] in this case all items used for comparison take a continuous part of the array and can be aggregated directly. and all items that can be returned take a continuous part of the array and can be aggregated directly.
