Not quite. In c++17 throw() was redefined to noexcept, but prior 
to this it should unwind the stack with unexpected as the 
exception. Noexcept may or may not unwind the stack and allow 
optimizations.

Noexcept is now part of the function type and you can test 
expressions with the noexcept operator. I believe it is more to 
support generic programming and optimization than to prevent bad 
behaviour.
