David:
Why does dmd produce this warning? (this is new in 2.063) Why is assigning elementwise better?
The short answer is: do as the compiler suggests you, and be very happy the compiler avoids you some bugs.
The explanation is longer. In brief, it's much better to avoid some bugs and to make the D semantics more clear, to denote all vector ops, including the assignment with a [].
