Houghton Mifflin Harcourt. How to read these tables: shown are the runtimes of the Any tests, normalized relative to the runtimes of the same Foo tests. Shouldn’t destruct be one, too? We have almost 200 lists of words from topics as varied as types of butterflies, jackets, currencies, vegetables and knots! My short initial answers to these two questions above are "no" and "not without the help of the compiler", respectively. Yes.

Destroy or destruct? Finally, I made operator delete protected instead of private, so that derived classes can reuse it in their destroy() implementations and don’t have to define their own operator delete. As a result, only destruction through object reference variables (i.e., pointers or references) could incur this overhead; static and automatic objects will not suffer from it. For years, use of destruct was tied to its 20th century origins, appearing mostly in aerospace and military contexts and in the occasional cloak-and-dagger story.
