Go examples and idioms [closed]

There’s not a lot of Go code to learn the language from, and I’m sure I’m not the only one experimenting with it. So, if you found out something interesting about the language, please post an example here.

I’m also looking for

  • idiomatic ways to do things in Go,
  • C/C++ style of thinking “ported” to Go,
  • common pitfalls about the syntax,
  • anything interesting, really.
