Forward-declaring class templates is as easy as a normal class declaration: template class X; It is also possible to provide forward declarations for specializations of those class templates: template class X; template <> class X; If no user-declared prospective destructor is provided for class T, the compiler will always declare one (see below), and the implicitly declared prospective destructor is also the destructor for T .

Compared to Q_GLOBAL_STATIC, and assuming that MyType is a class or struct that has a constructor, a destructor, or is otherwise non-POD, the above has the following drawbacks: it requires load-time initialization of MyType (that is, the default constructor for MyType is called when the library or application is loaded); As you said, if some of these destructors touch already destroyed objects, your program could crash. UUID creation was the slowest part, the optimisations I suggested above seemed to help improve it, at least in my benchmarks. Creates and returns a new key object containing a public key.
