How do I make an item in a description list verbatim? \verb in \item[] seems to be not allowed:
\begin{description}
\item[\verb+list comprehension [f a | a <- M a]+] bla bla bla
\end{description}
[Tex/LaTex] Verbatim description list item
descriptionlistsverbatim

To expand a bit on some of the other answers: here is a modification that does not change the syntax of the description environment:
\documentclass{article}
\usepackage{hyperref}
\usepackage{nameref}
\makeatletter
\let\orgdescriptionlabel\descriptionlabel
\renewcommand*{\descriptionlabel}[1]{%
\let\orglabel\label
\let\label\@gobble
\phantomsection
\edef\@currentlabel{#1}%
%\edef\@currentlabelname{#1}%
\let\label\orglabel
\orgdescriptionlabel{#1}%
}
\makeatother
\begin{document}
\section{Definitions}
\begin{description}
\item [Vehicle\label{itm:vehicle}] Something
\item [Bus\label{itm:bus}] A type of \ref{itm:vehicle}
\item [Car\label{itm:car}] A type of \ref{itm:vehicle} smaller than a \ref{itm:bus}
\end{description}
The item `\ref{itm:bus}' is listed on page~\pageref{itm:bus} in section~\nameref{itm:bus}.
\end{document}
Use \footenotemark inside the item's optional argument and \footnotetext outside.
\documentclass{article}
\textheight=80pt% just for the example
\begin{document}
Text text text.\footnote{This footnote is working.}
\begin{description}
\item[Label\footnotemark]\footnotetext{This footnote is working, too.} Some description
\end{description}
\end{document}

The package
examplepprovides several commands and environments for typesetting verbatim text. For instance, the robust commands\PVerb[options]{text}and\Q{text}can be used in macro arguments and in section titles as well.Code example for your description list:
Output:
See Verbatim phrases and listings in LaTeX by Péter Szabó (or
texdoc examplep) for further information. Escaping special characters (for instance with\Q) may be necessary as described in section 3.1 of the documentation.Note, T1 font encoding has to be use to get a proper < symbol because it's unavailable in standard OT1 encoding.
