Array append performance 2

Maybe the D specs have to be fixed then.

Right, but the following program:

import std.stdio: writefln;
void main() {
    alias int[2] T;
    writefln(T.init);

    int[2] T_init;
    writefln(T_init);
}

prints:
0
[0,0]

So if I have a dynamic array of static arrays (where T is the static array) I can't do this:
array[0 .. $][] = T.init;

I have to do:

T T_init;
array[0 .. $][] = T_init;

While if T is a dynamic array I can do:

array[0 .. $] = T.init;

So even if they aren't bugs I don't like all such differences much...
