There is proposal by Herb Sutter for add similar functionality to ISO - 
std::unwinding_exception 
http://isocpp.org/blog/2013/03/n3614-unwinding-exception , 
http://isocpp.org/files/papers/N3614.pdf which is aimed on providing 
basis for implementation of scope(failure)/scope(success).

Emil, could you please clarify what is your position on adding 
uncaught_exception_count into Boost.Exception? ( 
https://github.com/panaseleus/stack_unwinding/blob/master/boost/exception/uncaught_exception_count.hpp 
)
