As does R :)

    > c(1, 1, 1) + c(2, 2, 2)
    [1] 3 3 3
    > matrix(c(1, 1, 1, 2, 2, 2, 3, 3, 3),
    +        ncol = 3, byrow = TRUE) +
    + matrix(c(4, 4, 4, 5, 5, 5, 6, 6, 6),
    +        ncol = 3, byrow = TRUE)
         [,1] [,2] [,3]
    [1,]    5    5    5
    [2,]    7    7    7
    [3,]    9    9    9

Not quite so concise and elegant but it's pretty straightforward stuff for most R users.
