# Shorthand for deep enumitem

I am trying to make an outline that may need to go 5 layers deep. In doing my research, I found this which allowed for lists to go 9 layers deep apparently.

In testing it out I found that this works, however, I would like to use the shorthand that looks like this

\1 first label
\2 second
\3 third
...


How could I set it up so I can use that pretty short hand? thanks!

The easylist package provides close to this functionality. Here's an example from the documentation:

\documentclass{article}
\usepackage{easylist}
\begin{document}
\begin{easylist}
§ First proposition.
§§ Interesting comment.
§§§ A note on the comment.
§§§ Another note.
§§§§ By the way...
§§§§§ This is a subsub...-proposition.
§ Let’s start something new...
\end{easylist}
\end{document}
