What is supposed to happen when an exception is thrown within the "finally" block? Being a C++ person, I half expected the program to terminate, but a look at the exception handling code for D shows that finally blocks have their own hidden exception handler. It looks like the intent is to ignore any exceptions thrown in the "finally" block and to rethrow the original exception. Is this correct? For comparison, I wrote some .NET test code and it looks like as far as .NET is concerned, the exception generated by the "finally" block is thrown and the original exception is dropped. I'm not sure I'm completely happy with either practice, but calling terminate() seems like it may be overkill. One dirty solution would be to chain exceptions together using the next reference in the Error class, but the chained errors wouldn't be truly handled without all sorts of TypeInfo stuff in catch blocks. How do other languages handle multiple in-flight exceptions? Are there any that do? Sean
