Static local variable in Go

Question

Is it possible to define a local variable in Go that can maintain its value from one function call to another? In C, we can do this using the reserved word static.<

Answer 1

You can do something like this

package main

import (
    "fmt"
)

func main() {
  f := do()
  f() // 1
  f() // 2
}

func do() (f func()){
  var i int
  f = func(){
    i++
    fmt.Println(i)
  }
  return
}
