They can act like the base type up to a point. You make it sound like a
chore to use a wrapper type, but the truth is they are easy to use,
there are not that many cases to worry about.
My experience with wrappers in C++ has been similar to Rainer's.
Essentially you can't define "smart references" in C++. I hope we were
or will be able to fix that with the "alias this" feature.
