In C# I declare arrays of arrays as

   byte[][]  array1 = new byte[cAllocs][];

    // Allocate all indexes
    for(j = 0; j < cAllocs; ++j)
    {
     array1[j] = new byte[ . . . ];
    }

In D, this does not work. It has to be

   byte[][]  array1 = new byte[][cAllocs];

    // Allocate all indexes
    for(j = 0; j < cAllocs; ++j)
    {
     array1[j] = new byte[ . . . ];
    }

Is this correct? It seems contradictory.

A quick answer by anyone on this would be _greatly_ appreciated. :)

It's correct. Note that the new syntax matches the declaration syntax.
