"Go Pro" is unfortunately a very misleading name. I just spent an hour cleaning up his use of Go. Nobody made any attempt to actually turn this code into a well-written Go program. I did not realize that he was going to publish it externally.
Would you consider touching up the Go version again to make it more idiomatic and well written? I'd be interested in seeing good Go examples; I'm sure many others here would as well.
The Go distribution already contains plenty of idiomatic, well written and very readable code.
It would be interesting if you did the necessary optimization and posted your results for a better comparison.
