I second this. Volunteers are sorely neede
That's a nice read, thanks for the pointer. I agree with the solution
presented there. If we can do that it will be awesome. If help is needed I
can spend some time on it.
One of the things that I noticed is that the code can be optimized
significantly if we know the common case so that we can opt
