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.
That's a good idea, thanks. -- Andrei
