Multiple assignments are not working like in Go

[tkaehn]

The following program fibs.go doesn't run the same way like in Go:

package main

import "fmt"

func main() {
	a, b := 1, 1
	for i := 0; i < 10; i++ {
		fmt.Println(a)
		a, b = b, a+b
	}
}

Expected result:

$ go run fibs.go 
1
1
2
3
5
8
13
21
34
55

Got:

$ yaegi fibs.go 
1
2
4
8
16
32
64
128
256
512
