It's not safe. Multiple goroutines can enter the 'default' case in
that select and close() the channel multiple times.

That looks really neat. I will dive into the code!
I'm very curious how the performance of Skylark in Go compares to Skylark
in Java (and CPython 3.6 for that matter) -- any benchmarks on that?

Thanks, Dave! Using [[override]] fixed the problem

Hi
Here is the code:
Version 1:

"sync"

var once sync.Once
func setup() {
a = "hello,world\n"
}
func doprint() {
once.Do(setup)
fmt.Print(a)
}
func twoprint() <-chan struct{} {
var wg sync.WaitGroup

go func() {

Hi there, how are you doing?
I'd like to get a time.Time 1h hour in the past. I see in the documentation
that Go has a time.Add functions, it would be something like this, but for
subtraction.
The time.Sub function returns a Duration type, and I need a Time type.
Thanks!

This looks neat. Are you able to provide more context on what this is/will
be used for at Google?

You absolutely can use goroutines without waitgroups! It all depends on
what you are doing with them. Where waitgroups come in is when you need to
something only after *all* of the goroutines on a specific task are done.
Chances are that if you are not using waitgroups, you are either using
cha
And technically they are not tracking goroutines but done things. Each
goroutine could each finish 10 things.

I am new to Go and I had read numerous times in various articles that one
can technically create any number of Go routines and the runtime takes care
of them mapping to kernel threads. If so, why does waitGroup designed in a
way such that one has to specify how many go routines one need to creat
