If C++ code can execute D delegates, perhaps an intermediate step 
would be to create a wrapper in C++ that calls the delegate 
wrapped in an appropriate try/catch block.  Syntax would be a bit 
weird as you'd have to specify a callback for each exception type 
you wanted to catch, but it seems doable.
