yeah, that's the "curiously recursive template pattern". The 
thing is that all these classes don't actually derive from a 
common base. The fact that they have a base class is only an 
implementation detail.

This trick is used a lot in C++, but in D, I really don't see 
what you get doing this over a simple template mixin (appart from 
not being able to have a "true" base class)...
