Yes, you're right.  Then it disappeared for a while when I shifted 
list management over to "genr"; but now it's back again.  And in 
its new incarnation it's more flexible: the matrix on the right 
doesn't have to be a pre-existing named matrix, it can be some 
expression that evaluates to a matrix, e.g.,

matrix m = {1,2,3,4}
list L = m .+ 1
