Oh, and it should work the same for cube types:
R> cppFunction("void test2(arma::cube & x) { x(0,0,0) = 0.5; }",
R> depends="RcppArmadillo")
R> v <- array(sqrt(1:8), c(2, 2, 2))
R> v
, , 1

[,1] [,2]
[1,] 1.00000 1.73205
[2,] 1.41421 2.00000
, , 2
[,1] [,2]
[1,] 2.23607 2.64575
[2,] 2.44949 2.82843
R> test2(v)
R> v

Proxy object that still connected to the outside object, unless a cast is
needed (int <-> double), or a copy is enforced (clone(), possibly via as<>()).
