Proposal: lo.ClonePtr

[rot1024]

Often I want to duplicate a pointer easily. It would be useful to have a function that makes this easy:

func ClonePtr[T any](t *T) *T {
	if t == nil {
		return nil
	}
	u := *t
	return &u
}

Example (cloning URL):

u := lo.Must(url.Parse("https://example.com"))

v := lo.ClonePtr[url.URL](u)
// u and v are *url.URL

Maybe calling it ShallowCopy?
I think people need to be notified that the new instance share something(the reference field, like User field in URL) with the old one.
