The following program sample.go triggers an unexpected result

package main

import (
	"fmt"
	"slices"
)

func main() {
	s := []string{"Bat", "Fox", "Owl", "Fox"}
	slices.Sort(s)
	fmt.Println(s)
}

// Output:
// [Bat Fox Fox Owl]

Expected result

$ go run _test/slices.go
[Bat Fox Fox Owl]

Got

$ yaegi _test/slices.go 
run: 16:19: undefined selector: slices.Sort

# After editing stdlib/generic/go1_22_generic.go 

$ yaegi _test/slices.go 
run: 16:19: undefined type for E

Additional Notes

First seen while trying to use OTEL from inside a Traefik middleware:
