h typesetting Mathematica's double-bracketed
  subscripting command using <code>[[</code>...<code>]]</code>
  in my documentation chunks.
noweb considers <code>[[a[[#]]&amp;]]</code> to mean the symbols <code>a[[#</code> in 
typewriter and then latex gets stuck on the offending <code>&amp;</code> character.
How can I get around this problem?

<p><blockquote><b>A.</b>
Split the quoted code into two
pieces, which you write consecutively, thus:
<blockquote>
  <code>[[a[[#]]]][[&amp;]]</code>
</blockquote>
