mikera: matrixes are seqable and can be passed to transducers to be processed in a row wise fashion can't they?

though I'm guessing it will throw away all the matrixy goodness as it goes through the transducer

Most matrices are seqable, but it isn't guaranteed, since someone could extend the matrix protocols to and arbitrary type. Best to call c.c.m/slices first to guarantee a sequence of rows
