It *isn't optional* if you aren't launching it with bash like:

     bash ./script.sh

Otherwise system won't know how to launch it.

Actually with shebang (that is how it called) you can run almost anything in "interpretator mode" (e.g. without prior compiling).

Notable exception is Go (and there are some others):

---code start

///usr/bin/env go run "$0" "$@" ; exit

package main

import "fmt"

func main() {
         fmt.Println("Hello, world!")
}

---code end

Kind-of shebang, but not shebang.

Anyway, shebangs are useful mostly for interpretators like shell variations, python, perl and so on. Example above isn't really useful because Go will compile in native machine code (read: produce runnable binary file) blazingly fast.
