Walter,

 Here is a simple change I'd like to see to Exception:

class Exception {
+  static void* function() exceptionHook = null;
+  void* hookData;
}

 If the application sets the global exceptionHook this function is called in the context that generated the exception (ie. with the stack intact). The return value is attached to the Exception created.

 This would enable client implementation of stack tracing, crash dumps and
similar features without burdening the language or compiler. Currently
implementing crash recovery is brittle at best and impossibe at worst.

 Take care,

 Kai

 Just to be a bit more precise. There can naturally be a constant number
of additional stack frames on the stack (the exception processing routines)
or alternatively the hook function can take an int parameter giving the number
of extra frames.
