Interestingly enough you can have void as default type by simply using another

typedef void type;

template <class T, class R = VoidWrap::type>
struct Blub

Update:
-------
The port provides some helper-macros for convenient specialization
of std::less for Smart-Pointers.
If, for example, you want to use a Smart-Pointer as the key of a std::map,
you can do it like this:
[code]
#include <map>
#include <loki/SmartPtr.h>
SMARTPTR_SPECIALIZE_LESS(Apple)
class Apple {};
int main()
{
std::map<SmartPointer<Apple>, int> m;
