How does one initialize a static rectangular array (2-d matrix) in D1?

None of the following or other variations that I've tried compile with DMD 1.0.

int[2, 3] matrix = [ 1, 2, 3,  4, 5, 6 ];
..that's not how you declare a rectangular array type. It's int[3][2].

int[3][2] matrix = [[1, 2, 3], [4, 5, 6]];

Thanks Jarrett.

Am I having a blonde day?

   int[2,3] m = [ 1, 2, 3 ]; 
   writefln( "m=%s, .sizeof=%d", m, m.sizeof);

Compiles and prints:

m=[1,2,3], .sizeof=12

So what does that declaration, int[2,3], mean?

Think this is what threw me initially.

Thanks, Justin

2,3 is a comma expression. Evaluate everything, and return the rightmost 
value.
