Concurrency with goroutines and channels in Go is pretty awesome, as is the tooling: race detection, code formatting, PPROF performance monitoring, vetting (finding incorrect printf strings), and a great test framework with parallel execution support. The standard library is enough for most of what you'll need, and it's all open source, so you can learn to write idiomatic Go from it.
