Walter Bright:
struct Vec { float x = 1, y = 5, z = 9; }
auto v = new Vec(void);
auto av = new Vec[10] = void;
auto av2 = new Vec[10] = Vec(0, 0, 0);
D already does this.
D doesn't do that, not even one of those three :-) I'm willing to
open one or two ERs later on those things.
At best in Phobos we have a workaround for the second of those
three ideas:
auto av = minimallyInitializedArray(Vec, 10);
He suggests a way to optionally specify the type of array
indexes. In a D-like
syntax it could be:
enum N = 10;
float[N : ushort] a1;
float[: ushort] a2;
I don't see any point to this.
My point of having this in D is to optionally increase
strictness of the array
indexes, to avoid some bugs when you handle many arrays.
Doesn't make sense to me.
