- That is, overload operator delete with the placement syntax. We can provide
- extra versions of operator new with an arbitrary number of additional
- arguments, but there can be no additional arguments to delete other than
- those specified in the ARM.
-
- I don't have the ARM at home with me right now, so I can not recite chapter
- and verse.
