Public Functions

Type	Name
constexpr	Persistent () noexcept A constexpr constructor avoids the static initialization order fiasco.
	operator bool () const Check if this stores aClass instance yet.
Class &	operator* () Retrieve reference to Class instance, always returns the same reference.
Class *	operator-> () Retrieve pointer to Class instance, always returns the same pointer.

Detailed Description

Create an instance of Class on demand that is constructed and never destructed. Due to its constexpr ctor and on-demand creation of Class, a Persistent<> can be accessed at any time during the static ctor (or dtor) phases and will always yield a properly initialized Class.
