Vue3 SFC script setup top level variable name conflict with imported componented name

[liuchao92]

if

import HelloWorld from './HelloWorld.vue';

then i can not create a variable like this:

const helloWorld = {}

it will cause this warning:

Component is missing template or render function: [object Object]
 at <Anonymous>
 at <Repl>

complete example is in Vue SFC Playground

I have experience with Vue2, but is new to Vue3. I'm curious about this.
