Is there anyway to access a c++ defined class with D, or must all member
function calls be called from within the c++ code in order to have information
brought up.  Or is there a way to create a object of type myCPPlusClass  that
will allow for more direct access to the member functions of the class?  If it
is possible some example code of a working basic C++ class and it's calling
corresponding D code.  would be appreciated, I am trying to see if I am trying
to find a way to reuse some of my old C++ classes to test out the linking in
D2.0

For example if i wanted to have D do the interface, and C++ libraries handle
the back end math functions.

D can access C++ classes as long as those classes are single inheritance. Just 
mark them in the D declaration with extern (C++).
