The only time I have found it useful to have default-constructed objects
that are otherwise unusable is when I need to store them in a map or
other container that requires a default constructible object. That
allows me to use the easier operator[] syntax instead of using insert
and find. However, I've begun to view that as a defect in the interface
of std::map rather than a need to have default constructible objects
even when they are not usable.
