How can I reset a rectangualr array without having to loop through it?

int[][] myRectData = new int[][](10,10);

myRectData.length = 0;
myRectData[].length = 0;                
myRectData[][].length = 0;      

They all give: slice expression .. is not a modifiable lvalue.

This works form me:

//DMD64 D Compiler 2.072.2
import std.stdio;

void main()
{
    auto arr = new int[][](10,10);
    writeln(arr.length);
    arr.length=0;
    writeln(arr.length);
}

output:
10
0
