55 * October 2005: The following list terms have been optimized (from the
56 * original ASL grammar in the ACPI specification) to force the immediate
57 * reduction of each list item so that the parse stack use doesn't increase on
58 * each list element and possibly overflow on very large lists (>4000 items).
59 * This dramatically reduces use of the parse stack overall.
