I have no major problem with the additional macro BOOST_NOEXCEPT_NOTHROW
, but I don't see why it should be committed so quickly.
I will cal it BOOST_NOEXCEPT_OR_NOTHROW.
My question is what macro will you use you implement noexcept in
Boost.System. If you don't want to break c++03 compilers I think it
should be BOOST_NOEXCEPT. Could you confirm?
