Here's the style of code that causes me to reach for that little baggie:

void function() {
  try {
    doFirst();
  }
  catch (conditionA) {
    recoverA();
  }
  catch (conditionB) {
    recoverB();
  }
  try {
    doSecond();
  }
  catch (conditionC) {
    recoverAB();
  }
  try (conditionD) {
    doThird();
  }
  catch {
    recoverD();
  }
  try (conditionE) {
    doFourth();
  }
  catch {
    recoverFourth();
  }
}

I'm sorry that my tiny gripe spun off into such a contentious debate, 
but maybe, just maybe, it's a sign that exceptions aren't the 
wonderfully simplistic panaceas that people think they are. Perhaps 
there are some pitfalls and drawbacks associated with them.
