digitalmars.D.announce - D is now catching C++ exceptions!

This is what Andrei and I call "enabling" technology, as it opens the door for 
many more uses of D, in this case better interoperability with existing C++ 
codebases.

Thanks to everyone who helped out with this, especially Elie, Iain, David and 
Andrei!

Also looking forward to getting this in GDC and LDC!

Andrei and I feel that better interoperability with C++ is a major strategic 
feature and advantage for D. As the recent thread with Manu's frustrations in 
doing it show, we still have a significant way to go. But I hope to push it 
forward hard in the next few months.

For the fearless who love working under the hood, extending the support to the 
rest of the platforms is a great way to materially contribute.

Nice work! Although I've never used C++ exceptions (or D exceptions) personally.
Is there a roadmap for this stuff I can check out? Short list of
upcoming C++ work?

Since you're at the bleeding edge of interfacing to C++, I'd say your problems 
are on the short list :-)

Since we're nowhere on Win64 C++ exceptions at the moment, I guess it's good 
you're not blocked by them.

What is the state of C++ interfacing? is the

This is a good start and we should continue this work.
We need review our documentation about interfacing to C++ and 
clearly delineate the limits of our features.

For example we should say how do we may write D binding of C++ 
class.
How do we may inherit D-defined C++ class from external C++ 
class/interface?
When can we pass object of inherited class back to C++ code?
How do we may cast one extern(C++) class to another extern(C++) 
class in D?
In C++?
Which C++ features we support for different ABIs?


Also, I think, we need to implement linking to some C++ features 
(I'll help with this when I finish my alias this duty):
Linking to C++ overloaded operators (without moving their 
semantic to D).
C++ ctors/dtors.
Dynamic casting of C++ objects in D.
Maybe partial C++ RTTI support.

Next step, catching any foreign exception thrown in Go, Ada, Java, [insert
your language here].
