C++11 Unrestricted Union "Slot"

gistfile1.cpp

#include <utility>

// Is this mad?  The idea is to make a "slot" for an object but have manual initialization/finalization,
// rather than being constrained to C++'s semantics.  Useful, e.g., in Object Pools.  Is there a simpler
// way to get this effect?

template<typename T> 
union Slot {
	T inst;

	Slot() {}
	~Slot() {}

	template<typename... Args>
	T* init(Args&&... args) { return new(&inst) T(std::forward<Args>(args) ...); }
	void release() { inst.~T(); }
};
