Hi Andrei,

Not yet but I've looked into it, the plan is to add:

   catch (C++) (...) { }

statements and make Clang translate them into C++ landing pads 
(as for imports the parser will query the language plugins when 
encountering two pairs of (), so the C++-specific statement will 
be part of Calypso, not DMD).

Then add a "C++ exception class" handler in LDC's personality 
function:

   
https://github.com/ldc-developers/druntime/blob/ldc/src/ldc/eh/libunwind.d#L327

Easier said that done but Clang should make the std::type_info 
matching doable.

So it's on the roadmap just after the merge of LDC 0.16.
