RAII is orthogonal to exceptions, so his claim is nonsense.
Just a note: this isn't really true. RAII was initially used to
deal with exceptions. If you want fast backtracking and just
reset the stack pointer (rather than unwinding) then
stack-allocated RAII objects won't work since they will be
overwritten. You need to maintain a list of "destructors" in
thread local memory or close to the stack root so that you can
close files etc. Whether RAII is the best option really depends
on what kind of execution patterns and performance
characteristics you are aiming for.
