Error using `show-example`

#import "@preview/tidy:0.2.0": show-example

#show raw: show-example.show-example

```typ
Hello world

Produces the error
```console

It's not really intended to be used like that. The bug is there for sure and easy to fix. However, show-example creates a new raw and that would result in a recursive show rule.

[Mc-Zen]

I can change that and prevent the creation of a new raw but show-example still wouldn't work quite as within docstrings because the scope is not passed down automatically and user-defined functions would not be available.

[Mc-Zen]

On the other hand, you could do which would work.

#let my-var = [34]
#show raw: show-example.show-example.with(scope: (my-var: my-var))

```typ
Hello world #my-var

Okay, I'll push some update that will allow doing that.
