我可以在切片中内联声明接口列表吗？

Question

package main

import (
    "fmt"
)

func main() {
    var a A
    var b B

    for _, v := range []WhatAreYou{a, b} {
        fmt.Println(v.Question())
    }
}

type WhatAreYou interface {
    Question() string
}

type A struct {
    string
}

type B struct {
    int
}

func (a A) Question() string {
    return "I'm an A"
}

func (b B) Question() string {
    return "I'm a B"
}

The code above works as I expect and calls the function on each interface as expected. Go Play

In my actual code I intend to have many different types implementing an interface. How can I get rid of the var a A var b B etc and simply declare them all in the slice? i.e. I tried and failed with the following and other variations

for _, v := range []WhatAreYou{a A, b B} {

Answer 1

[]WhatAreYou{A{}, B{}}

This is correct, thanks to mkopriva. Composite Literals

Now I understand a little better what I am doing here I think I understand why this question is down voted too. The question doesn't really make sense. I was so hung up on the idea of the interface I didn't think of anything else. var a A is declaring a struct that happens to implement an interface. This is even more obvious if you initialise the struct e.g. var a = A{"hello"} or inline A{"hello"}, B{2}
