go-workshop's Issues

keine Referenzmodifikation + Konstanten können nur Konstanten zugewiesen werden

	// Beispiel das es keine Referenzmodifikation gibt
	aa := "t"
	ab := aa
	aa = "s"
	println(aa)
	println(ab)
	
	
	// Konstanten koennen nur Konstanten zugewiesen werden
	const x = "hallo"
	const c = x
	println(c)
	
	// Konstante mit einer Variable initialisieren schlaegt fehl
	var v = "hallo"
	const d = v
	println(d)

Memory Allocation

It seems, that GO decides: look here

Example wrong

package main


import "fmt"
import "time"

func main() {
    var now = time.Now()
    fmt.Println(now)
}

delete() for slices?

defer after return?
