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

* ArgList, TermList, Objectlist, ByteList, DWordList, PackageList,
