The whole point of exceptions is that you don’t need to handle errors at every call site. You can just have one central try-catch block at a place where you have a way to deal with the error, such as report it to the user.

Not the person you are replying to, but did you see where he said:

Throwing lets you handle the new situation without changing the API at all.

See, that's what happens when you form your opinions on half-digested ideas. Let me be clear. You don't add "a bunch" of try-catch blocks. You don't wrap every call that's capable of failing exceptionally in a try-catch block. That's exactly how you don't use exceptions. The whole point of exceptions is that the compiler will handle the stack unwinding for you so you don't need to worry about it. If you don't want to, or don't know how, or can't handle an exception at a specific point then don't. Let it bubble up for someone else to catch. See the ellipsis in my example? Inside of it you might have a gigantic call tree that performs all sorts of different operations that may all fail in different and unexpected ways. You could write the whole thing and not have a single try-catch besides the one I wrote explicitly. Let me reiterate; this is what you DON'T do:

  try{
    foo();
  }catch (...){
    return Error1;
  }
  try{
    bar();
  }catch (...){
    return Error2;
  }
  try{
    baz();
  }catch (...){
    return Error3;
  }

The only reason you would do something like this is to satisfy a specification such that you have to return different errors, specifically when each of the different calls fails. So... don't specify your functions such that you're required to do this? Just do

  foo();
  bar();
  baz();

or if you really must not throw from the function,

  try{
    foo();
    bar();
    baz();
  }catch (...){
    return SomethingFailed;
  }

TL;DR: Instead of bitching about exceptions, learn how to use them properly.
