190    - In  all(M1 == M2)  for sparse large matrices M1, M2 (e.g. M2 <- M1 !),
191      the intermediate 'M1 == M2' typically is dense, hence potentially using
192      humongous amount of memory.
193      We should/could devise something like   allCompare(M1, M2, `==`)
194      which would remain sparse in all its computations.
