This is not how we're moving it.  The entire frontend will be moved in one 
go, there will never be a need to create a C++ class from D.

That said, the glue layer will remain in C++ and will need to create 
instances of classes defined in D.  The current glue layer calls 43 
different constructors.

I don't have a solution for this yet, but it will probably be:
a) Extend D to allow creating classes with constructors callable from C++
b) Create/generate factory functions for each class new'd in the glue layer
c) Remove all class allocations from the glue layer

I'm leaning towards b, or maybe c, and I think you should too.
