That works.

So I can write

    byte[] a = new byte[size];

and

    byte[][] a = new byte[][size];

but not

    byte[][] a = new byte[size][];

or

    byte[][] a = new byte[size][size];

let alone

    byte[size][size] a;


BTW, somebody on stackoverflow just posted an alternative
that comes closest to what I was looking for.

    byte[][] a = new byte[][](size, size);

I saw this notation before but I can't remember where.

Hey, I love D but it can be pretty confusing sometimes :)

Thanks
