This evolved into std.array.uninitializedArray.

One case worth considering:

auto mat = new int[5][5];
foreach (row; mat)
row[] = 10;

The way used to initialize a matrix to void is useful to initialize all of it
to a defined value too.

Nicer and cleaner:

// doesn't initialize foo1
auto foo1 = new uint[5] = void;

// initializes the dynamic array to 5, avoiding a double initialization
auto foo2 = new uint[5] = 5;

That syntax is inspired by static array syntax:
uint[5] a1 = void;
uint[5] a2 = 5;

Reassigning this to David. David, this is a sensible primitive. You may want to
make it into a pull request, probably in std.array or even in druntime. A few
notes:

1. newVoid is not very indicative, I'd suggest something long and
obvious-looking (as this can be an unsafe function), e.g.
makeUninitializedArray!int(100).

2. Since 0 seems to be an actually used constant of GC.BlkAttr, you may as well
give it a name, e.g. NONE.

Thanks!
