"Well, the feature was in the language so I figured I
should use it.". It is our belief that this is not a
sufficient criteria for using a feature of C++. A feature
should be used only when it can be demonstrated to be
of benefit. A mountain is climbed "because it is there".
The same should not hold true for C++ features. Their
mere existence is not justification for use.
