I'm usually working with positive values, and almost always with values within the range of integers f32 can safely represent (+- 16777216.0).

I want to be able to write `draw(x, y)` instead of `draw(x as u32, y as u32)`. I want to write "3" instead of "3.0". I want to stop writing "as".

It sounds silly, but it's enough to kill that gamedev flow loop. I'd love if the Rust compiler could (optionally) do that work for me.
