等效于Go的Rails控制台

I am relatively new to Go and I was curious if there is a console that I can test go commands in. I essentially want a sandboxed environment that resets every time the console is opened. For those that know Rails, a experience similar to Rails console is desired.

I'm not familiar with the Rails console, but the Go Playground (http://play.golang.org) provides a sandboxed environment to test Go code in. But it needs to be a complete Go program, not just typed in a line at a time like the console for an interpreted language like Ruby.
