or this,
printS, err := conv(func(s string, err error), fmt.Println) or panic(err)
_, err := []string{"hello}.Map(strings.ToUpper).MustEach(printS) or
panic(err)
count, err := conv(func(n int), fmt.Println) or panic(err)
n := []string{"hello}.Map(strings.ToUpper).Sum(count)
count, err := conv(func(n int, err error), fmt.Println) or panic(err)
n, err := []string{"hello}.Map(strings.ToUpper).MustSum(count) or panic(err)
that'd be great...
