Const system does not allow certain safe casts/conversions involving deep
composite types. In the following example, all casts should be allowed.
----

void testcases()
{
        int[][] intArrayArray;
        int[][][] intArrayArrayArray;


        const(int)[][] f1 = intArrayArray; // Error here
        const(int[])[] f2 = intArrayArray; 

        const(int)[][][] g1 = intArrayArrayArray; // Error here
        const(int[])[][] g2 = intArrayArrayArray; // Error here
        const(int[][])[] g3 = intArrayArrayArray;

}
