Steps to reproduce

1. Write a new component that makes use of $toRef but does not use $ref
2. You'll see the following error: $toRef is not defined

What is expected?

Transform kicks in when $toRef is used.

What is actually happening?

Transformation of $toRef does not happen unless the same file uses $ref.

It does not seem to matter whether $ref is used in a commented line of code.

Maybe this issue has fixed

I don't think so, I've just tested against v3.2.38.

Unfortunately, Reactivity Transform has been dropped officially now, so I closed this issue/PR. If you want to keep using it, please consider the community version Vue Macros.
