A recursive template generates infinite expansions.

Consider the following example:

template <class R1>
struct Base
{
};

template<typename R>
struct Derived :
  Base<
    typename Derived<typename Base<R>::type>::type,
    typename Derived<typename Base<R>::type>::type
  >::type
{};

R is instantiated as Base<R>::type, which causes another
instantiation of R into Base<Base<R>> etc...

This is not a solution, but a workaround.
