suggestion: functions describe about static variable about go-tour

[GoogleCodeExporter]

It's not a "static variable". Such a concept doesn't exist in Go. It's just a 
variable.

I knew there is no static variable in Go.  But, I think this method will let 
someone who want the static variable workable.

I want to track the number of times a method is called, and wanted to know if 
this could be done in Go. 

I applied the code snippet above to solve my problem, but no luck. 

func f() func() int {
  i := 0
  return func() int { i++ ; return i }
}

func meth(){
for i := 0; i < 2; i++ {
    next := f()
    println(next())
    println(next(), next())
}
}

func main() {
  meth()
}

O/P: 
1
2 3
1
2 3

How do I make sure the value is retained between iterations here? I'm new to 
Go, so any help or suggestions would be greatly appreciated!
