Hi,
In Java/C# you can create purely static classes.
These are classes whose methods are all static, the classes
cannot be derived from or instantiated:
```
static class Algo {
void drawLine(Canvas c, Pos from, Pos to) { ...... };
}
```
Class in use:
```
Algo.drawLine(new Canvas(), new Pos(5, 3), new Pos(7, 9));
```
But why not have drawLine just be a free function?
```
import bluepandastuff.algo;
auto canvas = new Canvas();
drawLine(canvas, Pos(5, 3), Pos(7, 9));
// Or, using UFCS:
canvas.drawLine(Pos(5, 3), Pos(7, 9));
```
I turned Pos into a struct, seems like a typical value type to me.
