Emptying dst slice

[trajber]

is this behavior correct?
I was expecting the dst.Data to be empty after the merge since I'm using the Overwrite option.

package main

import (
	"fmt"

	"github.com/imdario/mergo"
)

type My struct {
	Data []int
}

func main() {
	dst := My{Data: []int{1, 2, 3}}
	new := My{}

	mergo.MergeWithOverwrite(&dst, new)
	fmt.Println(dst)
}

This works:

	dst := My{Data: []int{1, 2, 3}}
	new := My{}
	if err := Merge(&dst, new, WithOverwriteWithEmptyValue); err != nil {
		t.Error(err)
	}
	if len(dst.Data) > 0 {
		t.Errorf("expected empty slice, got %v", dst.Data)
	}
