C++: How do I overload the "new" operator for placement new?
Consider the scenario:
T* t = new T();
X* x = new (t) X();
How would I do an overload of class T to allow this?

class T has no influence on how the statement X* x = new (t) X(); compiles. It will look for a suitable operator new (e.g. operator new(size_t, T*) or operator new(size_t, void*)) within the class scope of X, and then if none is provided there, in global scope, but it won't look inside T.
