A couple of extensions to `with` that would be worthwhile

I prefer with() while using the arsd.simpledisplay because it's 
needed a scope.

However, when you use double with(), an issue to come up! 
Compiled as follows, my only solution is:

```d
Painter window;
with(Color) window = new Painter("AxialPCB", black, gray, red);
with(window)
{
  //...
}
window.Handlers.eventLoop(0);
```
The new ideas are great about with() like the same inline import! 
If I used this way, it can't access it from the outside:

```d
with(new Painter("AxialPCB", Color.black, Color.gray, Color.red) 
{ //*/ }
```
