This complex solution for Fizz Buzz in Go caught my attention. Decided to write a simpler version for comparison. Still trying my to grok the former code which uses Go's channel to implement concurrency. It has been a while since I last read Go's code, let alone such complex one (for me). Still a lot to catch up.
On a related note, Fizz buzz, which I always thought the typical common way to filter programmer who can or can't code, is actually a children game that teach them about division.
