Shadowing constants

• constants can be shadowed as well, but it is not a good idea to do so.

package main

import (
	"fmt"
)

const pi float32 = 1.1

func main() {
	fmt.Println(pi)

	const pi float32 = 2.2
	fmt.Println(pi)

	{
		pi := 3.3
		fmt.Println(pi)
		pi = 4.4
		fmt.Println(pi)

	}
	fmt.Println(pi)
}

1.1
2.2
3.3
4.4
2.2

It is declared both outside the main function and inside of it.
