| <p>C++ is a complex language and an evolving one, and its standard |
| definition (the ISO C++ standard) was only recently completed. As a |
| result, your C++ compiler may occasionally surprise you, even when its |
| behavior is correct. This section discusses some areas that frequently |
| give rise to questions of this sort. |
