-<p>All the logic here should be moved into a separate function in
-c-typeck.c, named something like parser_build_c_cast. The point of
-doing this is, the less code in Yacc input files, the easier it is to
-rearrange the grammar and/or replace it entirely. Also it makes it
-less likely that someone will muck with action code and then forget to
-rebuild the generated parser and check it in.</p>
-
-<p>We also want to minimize the number of helper functions embedded in
-the grammar file.</p>

<li>Break up enormous functions.
<p>This is in the same vein as the above, but significantly harder,
