I don't agree that my proposal breaks existing code. The compilers of C
++0x have a lot of ways to solve this. For example, the compilers can
skip overriding operator new/delete and use the default
implementation. And they can give a warning that reminds programmers
to eliminate useless codes. Why do I think to cancel overriding the
DEFAULT operator new/delete is possible? Because overriding the
DEFAULT operator new/delete only change the implementation, not the
semantic (the concept). If implementations changes the semantic of
DEFAULT operator new/delete, they are bad code indeed.
