I think Ed is getting 'sort' mixed in there. Gunnar's
right, Ed. You can't just make syntax up. (Well, not
without a lot more programming, anyway.)
: Did you possibly consider to use the Reorder method?
This is a tough one. You need to supply a list of keys
to the Reorder() method. Getting the list of keys already
sorted by value may not be apparent to a beginner.
If "$t->SortByValue()" sorts the hash by values, then
"$t->SortByValue()->Keys()" will return the keys for that
sort. We want to supply the reverse of those keys.
$t->Reorder( reverse $t->SortByValue()->Keys() );
