The one thing that stopped me from implementing this is that the "|" character, almost unversally used to indicate vertical concatenation in matrix languages, is already taken by the "or" operation. It it feasible, in principle, to distinguish between the two uses: theoretically, given the expression "a | b" we first check that a and b are matrices with the same number of columns; if not, "|" should be interpreted as "or". I fear this could end up being a bit confusing, though.
