Oh, I think I was looking at the wrong code. I stand corrected. >> As far as I understand it, Sebastian introduced dependent (i.e. wrapped) >> exceptions in order to support capturing and rethrowing an arbitrary, >> potentially foreign exception via std::exception_ptr. > > In gcc, yes.

I went and read through the cxx-abi-dev discussion, and I see the necessity of dependent exceptions now even for non-foreign exceptions. I would appreciate it if we changed the name in our implementation to "envelope exception" or something like that; overloading "dependent" is quite unfortunate.
