Return in finally

[Frank Benoit (keinfarbton)]

If i understand your idea right...

class FinallyException : Object {} // Special excecption to enter a
finally block.
class Throwable : Exception {} // Base of all Java Exceptions

Now, instead of finally use only catch blocks

catch( FinallyException fe ){
 ...
}

Hm, i need to think more about it...
The FinallyException can be used to transport a thrown exception
At (1),(2) and (3) a return(val) or throw can happen.

// Java ==========================
try{
  // (1)
} catch( IOException e ){
  // (2)
} finally {
  // (3)
}

// D ==========================
auto fe = new FinallyException();
try{
  try{
    // (1)
    throw fe;
  } catch( IOException e ){
    try{
    // (2)
    } catch( Object e ) {
      fe.store(e);
      throw fe;
    }
  }

}catch( FinallyException fe ){
  // (3)
}
fe.throwIfHasException();


Does this work? oh, my brain hurts :)

Another thought, what about the performance, if an exception is always
thrown to reach the "finally" block? is that an issue?
