简洁地返回一个指向Go语言文字接口的指针

Question

Is there a more succinct of casting a literal into an empty interface? A lot of the relevant community issues are about coercing an interface to a literal but not vice versa.

Looking for something of the form:

func pointerInterfaceOf(in interface{}) *interface{} {
    return &in
}

I have tried

&reflect.ValueOf(in).Interface() // Compiler error

But that is a compiler error.

If you want to cast something to interface{}, just use the normal casting syntax:

interface{}(whatever)
