> we know that the function `start`returns nothing
Which is cool, but start is a (recursive) helper function for the go function (and if you look at the source file, there are a number more that are defined along with it, this is kind of a weird excerpt to just show the main go function and the first of several helpers), which is be the main public interface being defined in the code presented. I wasn't trying to describe what it looked like start did when called, but what it seemed like go was trying to do.
(And, I was doing so looking just at the excerpt and going a bit off the cuff; its clearly, looking at the source file, doing a lot more.)
