That's true, but when just moving through a range, the pointer
is the only thing that changes. The stuff it points to can still
be immutable.

I think the error you receive reduces to this:
import std.range: isForwardRange;
void foo(R)

I think the error you receive reduces to this:
import std.range: isForwardRange;
void foo(R)(R r) if (isForwardRange!R) {}
void main() {
immutable arr = [1, 2];
foo(arr
I'm confused, what am I doing wrong here? This example came from the
std.algorithm documentation.
import std.algorithm;
void main()
{
immutable int[] arr = [ 2, 3, 1, 5, 0 ]; // index using pointers
auto index1 = new immutable(int)*[arr.length];
makeIndex!("a < b")(arr, index1);
}
Your example with reduced boilerplate code:
struct DVECTOR2 {
template Accepts(T){enum Accepts=is(T==DVECTOR2) || is(T==float) ||
is(T==D3DXVECTOR2) || is(T==POINT);}
template isScalar(T){enum isScalar=is(T==float);}
float x = 0f, y=0f;
this()(float x, float y) {
this.x = x;
this.y = y;
Hi!
I've made a two dimensional vector structure (x, y) which is very
primitive, the only real thing that I want to do with this structure
is support for nearly all operators and support for D3DXVECTOR2 and
POINT structures.
While writing this structure the boilerplate code has steadily
