Aye, I'm just saying that there's *incentive* to new it, since it 
allows for reducing the two steps of declaration and setting the 
length into one. (and does compile without warning, at least with 
dmd)

You'll have to agree though that, by analogy, it's not unlike 
separating declaration from instantiation.

     SomeClass sc;
     sc = new SomeClass();

     string foo;
     foo = "moo";

     int[] arr;
     arr.length = 5;


I would not object to a syntax like T[](length), myself. My main 
pet peeve remains array literals being dynamic.
