WARNING -- THE FOLLOWING TECHNIQUE IS RECOMMENDED ONLY FOR
PEOPLE WHO ARE SURE THEY KNOW WHAT THEY'RE DOING.

To construct an object of class T at location x, do the following:

	void* operator new(size_t, void* p) { return p; }

	// ...

		new(x) T;	// construct the object

This effectively calls T::T() and tells it to do its thing
at location x.
