I think that this code should be possible, and that the current error is

[test23.d]
int[] arr = [0,1,2,3];
int[arr.length] arr2;

void main()
{	
}

C:\Library\D\src\temp\test23.d(2): no property 'length' for type 'int[]'

The same occurs for a static array.

[test23.d]
int[4] arr = [0,1,2,3];
int[arr.length] arr2;

void main()
{	
}

C:\Library\D\src\temp\test23.d(2): no property 'length' for type 'int[4]'

I think that (at least) this latter example should be valid. Ideally both  
examples should be valid code as the length is clearly known at compile  
time.

In fact:

[test23.d]
int[] arr;
int[arr.length] arr2;

void main()
{	
}

would also technically be valid assuming "int[0] arr2;" was valid.

Yep, I think you're right. Should be possible.
