A better way to do nested lists

This is how you type set a nested list in LaTeX:

\begin{itemize}
\item I have a house
\begin{itemize}
\item It has 4 walls
\item a roof,
\item two windows,
\item and a door
\begin{itemize}
\item with a handle
\item and a lock
\end{itemize}
\end{itemize}
\item I also have a car
\begin{itemize}
\item but I will not talk of it further
\end{itemize}
\end{itemize}


This is the same list in Markdown:

 - I have a house
- It has 4 walls,
- a roof,
- two windows
- and a door
- with a handle
- and a lock
- I also have a car
- But I will not talk of it further


The Latex one is really verbose. I am finding it particularly annoying when writing slides with Beamer. Nesting 3 deep is rarely a good idea, but having a list that contains a few subitems for every item is not bad at all, but will still be uncomfortable verbose.

Is there a package that provides a alternative syntax for writing lists?

Using a few defs can help maybe, but seems hacky

\newcommand{\ol}{\begin{itemize} }
\newcommand{\ole}{\end{itemize} }
\newcommand{\li}{\item }


Parsing markdown lists syntax seems like it could be done with Lua, or maybe even with xargs, but I am not so great at this kinda thing (yet).

May be seeing indentation is a bit difficult, but you could, for instance, in a relatively simple way see - for \item and -- for \iitem where both are a little inteligent and start a new \begin{itemize} or end a \end{itemize} when necessary. –  Manuel Sep 3 at 17:41

Isn't it rather a problem of configuring your editor? –  Bernard Sep 3 at 17:54
@Bernard: no because the verbosity is not a just a typing problem (though it is that -- a missed end is annoying to find), it is also a reading problem –  Oxinabox Sep 4 at 0:11

Have a look for example at the easylistpackage. It simplifies the process by defining one active character whose number of occurences defines the level of this specific list item.

\documentclass{article}
\usepackage{easylist}
\begin{document}

\begin{easylist}
§ First level
§§ Second level
§§§ Third level
§§§ Again third level
§§§§ Now fourth level
§ First level again
\end{easylist}
\end{document}

\documentclass{article}

\newcommand{\ol}[1]{\begin{enumerate}#1\end{enumerate}}
\newcommand{\ul}[1]{\begin{itemize}#1\end{itemize}}
\newcommand{\li}[1]{\item{#1}}

\newlength{\shiftwidth}
\setlength{\shiftwidth}{3em}
\newcommand{\info}[1]{\par\hspace*{#1\shiftwidth}$\bullet$\quad}

\begin{document}

Simple ways to make lists less verbosely in \LaTeX:

\ol{%
\li{Redefine the markup commands to match HTML.}
\ul{%
\li{This means turning the list environments into commands.}
\li{This is actually less verbose than real HTML.}
\li{You do have to keep track of the end braces and (I think) comment out the newlines.}
}
\li{Define commands to insert horizontal space and bullets manually, as shown below.}
}

\info{0} This is level 0.
\info{1} This is level 1.
\info{2} And this level 2.

\end{document}
