A related (but not the same) problem I had with verbatim was to
include a file inside a verbatim environment.  I wanted to have
a file of sample LaTeX code that could be LaTeXed alone correctly
and then include that file verbatim as an appendix in another
document.  Of course, I could have copied the file in with my
editor, but I wanted changes in the sample file to be automatically
changed in the version in the appendix.  

The problem of course is that
\begin{verbatim}
\input examplefile
\end{verbatim}

only prints `\input examplefile'.  One can place the verbatim
commands in the examplefile, but then one can not use the example
file directly to generate the example.  A solution:

\def\bv{\begin{verbatim}}% necessary to use expandafter
\def\infil{\input examplefile}
\expandafter\bv\infil
\end{verbatim}

There may be a similar solution with more expandafters that avoids
the def's but at least this worked.
