\verb is always available.  It just does not work everywhere.  It is
easy enough to check whether you are in such a context: just juggle with
catcodes, read the next char, and look whether it is affected.

The problem is that where \verb does not work reliably, considerable
material (typically all) will already have been scanned and
catcode-assigned by TeX, and you can't say "oh, I intended this to be
verbatim, please reconsider".

Check out
<URL:http://www.tex.ac.uk/cgi-bin/texfaq2html?label=verbwithin>.  In
general, people manage to make do fairly well with those restrictions,
so a LaTeX-only variant of LilyPond-book (where you can compile the
original file) would certainly have its use cases.
