Try the 2nd usage, D is a very flexible language; moves towards
perfection!
```d
struct Sarma {
int i;
// mixin DownRange;
}
struct Foo(T) {
int[] array;
// 1. USAGE
auto opApply(scope int delegate(T) dg) {
foreach (ref e; array)
{

The reason for (2) is that in UFCS chains, the only thing you
really only care about is what kind of range it is that you're
dealing with, and maybe the element type. What exactly the
container type is, is unimportant, and in

Thank you Jonathan for that very detailed response.
This thread can end now unless others really feel the need to comment.

In idiomatic D, you'd use `auto` when either (1) you don't care what the
type is, you just want whatever value you get to be shoved into a
variable, or (2) you *shouldn't* care what the type is, because your
code shouldn't be depending on it, e.g., when y

I tried it and it seemed to work OK.
Wondering if there are any good reasons to use auto,
