[Go] Creating a slice from an array.

package main

import (
    "fmt"
    "log"
    "reflect"
)

func main() {
    langs := [4]string{"Go", "Python", "Ruby", "PHP"}
    slice := langs[0:4] // Upper bound excluded.

    // Print out the types of these variables
    fmt.Println(reflect.TypeOf(langs))
    fmt.Println(reflect.TypeOf(slice))

    if !(langs[3] == "PHP") {
        log.Fatal("Wrong value")
    }

    slice[3] = "Perl"

    if !(langs[3] == "Perl") {
        log.Fatal("Wrong value")
    }
}
