Suppress output for a group

Question

I have an \item style command where I need to be able to suppress output for the following text. I can do this with \nullfont, but that seems like a poor hack. Is there a declaration that will suppress all output, along the lines of an \sbox0 but that is a declaration and not a command?

Here's a minimal working example (the real \myitem and the context in which it is used are more complicated).

\documentclass{report}

\newcommand{\myitem}[1]{%
  \nullfont% <-- want a better way to do this
}

\begin{document}
  \begin{enumerate}
    \item[foo] show this
    \myitem{bar} suppress this
    \item[foobar] show this too
  \end{enumerate}
\end{document}

Note that this is similar to this question but I can't modify the original tex source and thus don't have a handler for the end of the text associated with the item. There aren't paragraph skips between items.

Since you say you don't have multiple paragraph entries you can use \par to end the item:

enter image description here

\documentclass{report}

\def\myitem{\setbox0\vbox\bgroup\def\par{\endgraf\egroup\par}}

\begin{document}
  \begin{enumerate}
    \item[foo] show this
    \myitem{bar} suppress this
    \item[foobar] show this too
  \end{enumerate}
\end{document}

Thanks David, this is basically working. What's causing the enumeration formatting problem for the foobar item? – Luke Apr 03 '13 at 15:05
@Luke sorry change final \endgraf to \par as in updated answer. – David Carlisle Apr 03 '13 at 15:55
Ahh, I understand this completely now. Thanks David. – Luke Apr 03 '13 at 16:15
