It would take many calls to the modified toupper to cost as much as
needlessly duplicating one large text file, and now you have to either
live with the dups or write your own in-place toupper <g>
None of the const/immutability ideas will take care of having to "copy
on write"; they were all more-or-less just ways of enforcing COW so
there wouldn't be mistakes.
