First of all rendering is not by definition I/O except in the trivial sense that all functions take input and produce output. A pure 3D rendering function takes game state as input and produces a list of triangles + attributes to draw as output.
Even if that were true it would only further validate my point.
> Do you have anything to back that up?
Yes, I already showed that Render.hs validates my point.
