    func try(fn func()) { fn() }
    func catch(fn func(any)) {
        if v := recover(); v != nil {
            fn(v)
        }
    }
    func throw(v any) { panic(v) }

    func fail() {
        throw("Bad things have happened")
    }

    func main() {
        try(func() {
            defer catch(func(v any) {
                fmt.Println(v)
            })
            fail()
        })
    }

Sorry.
