I am really into variable shadowing in Go!

shadowing.go

package main

import "fmt"

func Secret() (int, error) {
	return 42, nil
}

func main() {
	number := 0

	fmt.Println("before", number) // 0

	{
		// meet the shadowing
		number, err := Secret()
		if err != nil {
			panic(err)
		}

		fmt.Println("inside", number) // 42
	}

	fmt.Println("after", number) // 0
}
