Andrei thanks for finally sharing your thoughts on the matter :-)

I'll see what I can do this week-end to expand examples and write 
a tutorial.

As for what could be done in core D, I haven't struck anything 
blocking while writing Calypso. Exception catching is next after 
the first light of my Ogre3D demo, Clang will probably simplify 
handling of C++ exceptions a lot.
