Writing renderless components with <script setup> syntax

[dmitriykorobkov]

What problem does this feature solve?

For now, there isn't any possibility to write <script setup> SFC without template. I have to write old syntax setup function with return () => null;
I'm using renderless components for modifying behavior of components, which contains first ones as slots.

What does the proposed API look like?

I think, nothing should be changed. If there is no <template> section, compiler infer () => null as render function.

@posva How this comment helps to solve my issue? There is nothing about <script setup> syntax in it.

We want to keep the behavior explicit because of what the comment says

@posva How and where can I write/return noop render function using <script setup> syntax?

Use an empty template
