Feature-Idea: Adding support for coconut (functional python dialect)

[henningsway]

Coconut (https://coconut.readthedocs.io/en/latest/FAQ.html) seems to add very useful functional programming tools to python and can be used as a Jupyter kernel.

It could be promising to use this together with R in a Rmd/qmd-File.

You can sort of use this right now:

---
jupyter: coconut

# Coconut support

We're missing some styling, but it kind of works:

```{coconut}
"hello, world!" |> print
```

In general, any jupyter kernel should generally work with quarto, as long as that specific .qmd file does not mix different languages.

There are a few things we need to add for proper syntax highlighting of coconut cells. But if your goal is to get started, this works right now.

Ah, this is already great to see and it also works on my machine. :)

Should it be already possible to evaluate coconut code interactively, say by selecting the coconut kernel for interactive evaluation via Ctrl+Enter?

No, we do not currently have support for general kernels in the IDEs and editor modes.

It's a big project, and I don't know when we'll get to that: we do a lot of custom work for specific languages like Python, R, and Julia. We'd have to create a generic interface layer and then have kernel implementors add support for it.
