I'm sorry I did not make myself clear. The issue was not about the order (I
hadn't even noticed the difference between both version).

The issue is that the elements in the destination array (a) are destroyed and
then postblit recreated.

I'd have expected to see assignments instead.

I mean:
//----void main()
{
    S[2] a = [S(1), S(2)];
    S[2] b = a; //Fine postblit here
    a[] = b[];  //But HERE, please use opAssign.
}
//----
