--> Consider using the new 'dotMethods' functionality to define
cbind() and rbind() versions that work with Matrix.
+- In all(M1 == M2) for sparse large matrices M1, M2 (e.g. M2 <- M1 !),
+ the intermediate 'M1 == M2' typically is dense, hence potentially using
+ humongous amount of memory.
+ We should/could devise something like allCompare(M1, M2, `==`)
+ which would remain sparse in all its computations.
