It does, of course!

Ahhh, the playground is in a time vortex. Of course!

time.Sleeps happen instantly on the server, so there's no duration of time in which a running goroutine could observe anything.
When a Write happens, it just records the fake time and includes that in the JavaScript sent to the browser, which simulates time with JavaScript window setTimeouts.

Here are the runtime modifications, for the interested:

It's an exercise for the reader.

I would looooove to be able to turn something like that on for tests.
Also, major kudos for getting this done. The playground was super shiny before, but it's taken on a life of its own now. People might learn Go just to be able to run code that makes it do cool stuff ;-).

Great stuff, but did the changes break Codewalk? I'm seeing no code showing in Chrome on either Win 7 or OS X.
You're right. The codewalks are broken, probably as a side effect of the update. I will look into it.
Thanks,
Andrew

of course, the nice thing about virtual time is you get

I cannot set a d for func Sleep().
Here is the code:
package main
import (
"fmt"
"time"
)
var c = make(chan int)
func main() {
go send(0, 3)
go send(1, 2)
go send(2, 1)
for i := 0; i < 3; i++ {
fmt.Printf("%v %v\n", <-c, time.Now())
}
}
func send(v int, d 3.Second) {
time.Sleep(d)
c <- v
}
Here is the code:
package main
import (
"fmt"
"time"
)
var c = make(chan int)
func main() {
go send(0, 3)
go send(1, 2)
go send(2, 1)
for i := 0; i < 3; i++ {
fmt.Printf("%v %v\n", <-c, time.Now())
}
}
func send(v int, d 3.Second) {
time.Sleep(d)
c <- v
}

d should be a time.Duration -- "3.Second" isn't a valid type.
If you're trying to set a default value, you can't. You can just check in the function whether it equals zero and set it to a default.
