recover Calls in the Loop Bodies of Ranging Over Iterators Don't Work
123.
package main
import "fmt"
func main() {
defer foo()
panic(123)
}
func foo() {
for range 1 {
fmt.Println(recover()) // 123
}
}
123. But it prints <nil> then crashes (since Go toolchain version 1.23.0).
package main
import "fmt"
func main() {
defer foo()
panic(123)
}
func foo() {
for range iter {
fmt.Println(recover())
}
}
func iter(yield func() bool) {
yield()
}
