I consider it a bug that this compiles. You're overwriting
immutable data, which shouldn't be possible (without casting).

Assuming you meant `arr[0].b = 4;`. Just overwriting the mutable part of
bar[0] is ok, of course.
import std.algorithm;
struct Bar {
const int a;
int b;
}
void main() {
Bar[1] arr;
Bar bar = Bar(1, 2);
bar[0].b = 4;
move(bar, arr[0]); // ok
arr[1] = bar;// fail, why?
move(Bar(1, 2), arr[0]); // fail, why source parameter isn't
auto ref?
}
