[Boost-users] Enforcing CRTP with the MPL?

Hi there

Having a templatized base class B

template<class T>
class B .....

is it possible to enforce that a class D can derive from B IF AND ONLY 
IF the curiously recurring template pattern is applied, that is

class D1 : public B<D1> ... // ok, compile
class D2 : public B<X> ... // not ok, do not compile

???

Thx
Stefan
