This is really very clear and helpful, and I appreciate your 
taking the time.  I will place it on the wiki if that's okay.

Library support is surely one of the largest impediments to the 
adoption of D, and we ought to place some emphasis on updating 
the documentation here:
http://dlang.org/cpp_interface.html

How does it work when external APIs expect objects from the C++ 
standard library?  strings, and so on?  How about funny pointer 
types?  shared_ptr  etc?  std::vector, std::list?

Here is one C++ library used by many in finance (at least as a 
backup).  I think there might be a decent amount of value in 
making this usable from D.  (Trying to put my own interests 
aside!)  Paging Andy Smith ?

Are there any well-known C++ libraries that you have interfaced 
to ?  Could you give some examples of how long it takes ?

Would you be able to drop me an email about something else?  No 
contact info on your blog, but my domain is
