Is this code correct or logically sound?
```D
import std;
enum {side/depth/height and side/height
x,//0
y,//1
z //2
}
/**
Indicates wether a triangle faces an imaginary view point.
*/
bool triangleFacesCamera(float[3] tA, float[3] tB, float[3] tC) {
float r1, r2;
r1 = atan2(tB[x] - tA[x], tB

You need to be exact on what 'correct' is. The comment above
`triangleFacesCamera` says:
Indicates wether a triangle faces an imaginary view point.
There's no view point / camera position defined

Looks like 'copy' has the same overload issue.
A static array is not a range of any kind

But regardless of Salih's exact intent, the broader point is:
a non-ref overload could be added to Phobos. And that would
enable `a[1..$-1].phobos_put([2, 3])`. Which is what he asked

But you can do `dig.copy(buf[])` since a dynamic array is.
Apparently, we will not be able to get rid of the necessity of
using slices. 😀 Neither with "copy" nor with "put"...

I'm surprised that you can get 300 views in a month on a

It should be fine to have both a `ref` and non-`ref` overload for `put`,

Hi, there is a feature when working with the InputRange. I don't
know when it released available. May be somewhere D compiler
between v2.087 and v2.096 (works) but definitely not before
v2.087 (including)...
Anyone know this?
```d
import std.range.primitives;
void main()
{
auto arr = [0, 1]

Edit: The Phobos library I'm using is corrupted. That's why the
last line was giving an error. But has it always been poss
