Thanks for the note. I'd like to get to the bottom of this and make the Go test representative of best practices. A previous decision may have been made to favor an implementation that was measured to be faster at the expense of best practices [1], but that is not irreversible.
I am not a Go expert and I believe you are, and certainly @bradfitz is as well. If you two tell us definitively to change the Go implementation to better comply with best practices, I'll see that it's done for Round 6. I apologize if you feel we stepped on your opinions in any fashion. I really value your input in the project to date and hope it will continue.
