 % Test the order of expansion.  The example was given in the original
 % question that led to writing this package.  For the record, this
 % package (at some point) used 32 |\expandafter| to do the expansion
 % in the right order, which was better than other approaches; however
 % this counting ignores the large overheads due to other primitives.
