multidimensional array setting/slicing?

[Saaa]

Is there a easy way to set/read a multidimensional slice of an array?

I'd like to do something like this... :)

int array[][];
array.length=100;
array[].length=200; :  Error: slice expression array[] is not a modifiable 
lvalue

int array2[][];
array2.length=4;
array2[].length=2;
array2=[[1,2,3,4],[5,6,7,8]];

array[10..10+array2.length][150..150+array2[].length]=array2;
