If your draw code doesn't depend on any scoped state you can
use `function()` instead of `delegate()` to save a GC call.
`scope delegate` also works here and just reuses the stack.

I'm looking for a construct that mimics using(var)/with(var)
D
bitmap* b;
draw_with(b)
{
draw_pixel(red, 16, 16); //draw red pixel to bitmap b (b is
implied above)
}
