// example1.go
package main
func main() {
var y int // BAD: y escapes
func(p *int, x int) {
*p = x
}(&y, 42)
}
example1.go y escape to the heap
// example2.go
package main
func main() {
var y int
func(x int) {
y = x
}(42)
}
example2.go y is not escaped and why ??
// example3.go
package main
func main() {
a := 100
y := &a
func(x int) {
*y = x
}(42)
}
example3.go y is not escaped and why ??
