Doesn't it work to treat $in_scope like sizeof, declared with %token?
$in_scope isn't really left-associative in any meaningful sense.

You should leave out the braces here, and in the 'else', since there's
only one statement.

Also, please be sure that the indentation follows the GNU coding
conventions.  Substatements should be indented by two spaces.
(c-exp.y is not a great place to look for examples, since it's a mess,
but look at, say, frame.c.)

that the code block for the new $in_scope grammar rule was not
indented in the same way as the other blocks.  These should all be
consistent.
