Re: [boost] ScopeExit Review Begins Today

It is my understanding that if the 'push_back' throws, then program
flow will never reach the BOOST_SCOPE_EXIT block, so the internal
scope exits object will never be created, so it won't erroneously
remove an element.

This code would exhibit the behaviour you describe:

  BOOST_SCOPE_EXIT( (commit)(m_persons) )
  {
      if(!commit)
          m_persons.pop_back();
  } BOOST_SCOPE_EXIT_END
  m_persons.push_back(person);

but the original looks safe to me.
