'Course, that's not why I write: do you understand the new directives?
Namely, do you happen to know

- how (in)compatible they happen to be with the NS_... macros?
- are they less or more efficient?
- what caveats there are mixin' them with NS_... macros? (seems with
@throw you can raise anything, but NS_HANDLER would suppose there's an
NSException subclass in localException, would it not?)
- which way is better for which situations?

Perhaps I've overlooked something, but save for a short info along
lines of "are backward compatible with NS... macros, incompatible with
C++ exceptions" in the release notes I've found nothing on this subject
yet...

TIA,
