Is there plans to catching C++ exceptions in D?
I'd say no to such an idea.
I understand the difficulty of it. However, we should look into
it closely. Preventing D code from catching C++ exceptions
forces one to implement the driver/event loop/etc in C++, which
is quite unpleasant. It essentially takes C++ compatibility a
few good notches down.
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.
