Hello,
We are racking our brains to figure out what to do about
exceptions thrown from C++ functions into D code that calls
them.
A few levels of Nirvana would go like this:
0. Undefined behavior - the only advantage to this is we're
there already with no work :o).
1. C++ exceptions may be caught only by C++ code on the call
stack; D code does the stack unwinding appropriately (dtors,
scope statements) but can't catch stuff.
This is what SDC does.
2. D code can catch exceptions from C++ (e.g. via a
CppException wrapper class) and give some info on them, e.g.
the what() string if any.
This would require that druntime to be dependent on C++ runtime.
