If I didn't use "auto ref" or "ref", string would get copied,
wouldn't it?
auto ref doSomething(R needle, R haystack);
To avoid this, I would have to write a[0..$], b[0..$], which
is not nice. Right or wrong?
Wrong. `a[0..$]` is the same as simply `a`. A `string` is just
another slice: a pointer and a length.
Ah, I see. So strings don't get copied around and I can remove
ref, very good.
