I'm experimenting with the new RleArrays from DelayedArray, and I was happy to see most operations work seamlessly just like a normal matrix.

I often use the the very fast rowsum function to aggregate rows of matrix, but this does not seem to work on an RleArray. Is there an alternative to the rowsum-function in for RleArrays?
