Mismatch in behaviour

[pjebs]

The following program sample.go triggers an unexpected result

package main

import (
	"fmt"
	"github.com/traefik/yaegi/interp"
	"github.com/traefik/yaegi/stdlib"
)

func main() {
	i := interp.New(interp.Options{})
	i.Use(stdlib.Symbols)

	_, err := i.Eval(`package main`)
	if err != nil {
		fmt.Println(err)
	}

	_, err = i.Eval(`import "fmt"`)
	if err != nil {
		fmt.Println(err)
	}

	_, err = i.Eval(`
type Person struct {
	Name string 
	Age  int
}
`)
	if err != nil {
		fmt.Println(err)
	}

	_, err = i.Eval(`
func Z(args ...any) []string {
	typs := []string{}
	for _, v := range args {
		typs = append(typs, fmt.Sprintf("%T", v))
	}
	return typs
}
`)
	if err != nil {
		fmt.Println(err)
	}

	_, err = i.Eval(`
func personDetails() (name string, age int) {
	return "Peter", 9
}
`)
	if err != nil {
		fmt.Println(err)
	}

	_, err = i.Eval(`
var ZZ = Person{}
`)
	if err != nil {
		fmt.Println(err)
	}

	_, err = i.Eval("fmt.Println(Z(personDetails()))")
	if err != nil {
		panic(err)
	}

	_, err = i.Eval("fmt.Println(Z(Person{}))")
	if err != nil {
		panic(err)
	}

}

Expected result

[string int]
[main.Person]

as per: https://go.dev/play/p/nFe42FDiksg

Got

[string int]
[struct { Name string; Age int }]
