How?
Are you aware of

For DMD if the personality functions sees the C++ exception class
(3rd arg passed to the personality func) would it be hard to make
it look for C++ catch clauses?
With Calypso those catch clauses are std::type_info pointers
wrapped inside a D class so that cast() is used to differentiate
D catch clauses from C++ ones in the action table, and the
personality function match those std::type_info against the one
from the C++ exception header by calling the virtual function
type_info::__do_catch(type_info*).
A single personality routine handles both D and C++ exceptions,
and I don't think having a different one for C++ exceptions would
make things much easier. The tricky part for DMD is probably the
std::type_info generation.
