optimize the production build results

[edison1105]

Note that this is not a real bug, just an optimization item.

see Playground

It seems no need to wrap it as an IIFE.

setup(__props) {
  const msg = ref('Hello World!')
  return ((_ctx) => {
    const n0 = t0()
    _setInheritAttrs(false)
    _renderEffect(() => _setText(n0, msg.value))
    return n0
  })()
}

better is:

setup(__props) {
  const msg = ref('Hello World!')
  const n0 = t0()
  _setInheritAttrs(false)
  _renderEffect(() => _setText(n0, msg.value))
  return n0
}

Instead of msg, it could be anything, including n0, which is why there's an IIFE

We can use Block Statement
Or use compiler static analysis to adapted generation result

How can I solve the problem? Please tell me, thank you. I don't quite understand
