That frankly is the problem. I wish *all* of WWDC was under
NDA. I'm  
not a select or premier ADC member, either, and I didn't
attend. I'd  
just as soon not have to listen to all the pissing and
moaning from  
all the other people who weren't there complaining about
something  
they think they might possibly know.

I am not arguing that the evident demise of (large portions
but not  
actually all) of 64-bit Carbon is *good* news, but I feel to
see it  
is an unmitigated disaster for people writing code *now*.

32-bit Carbon won't be supported forever.
64-bit Cocoa won't be supported forever.
Some day, you're going to die.

Well, I can't run Classic applications on my MacBook...

And, as I understand it, the Java-Cocoa bridge that Apple
was promoting 
so heavily a few years ago is now very fragile.

No, but I do have a fairly large pile of Tcl and Python code
calling Tk 
routines, and I *am* nervous about that code no longer
working at some 
point in the future because the Carbon frameworks that
underpin Tk-Aqua 
have been deprecated and removed from OS X.

Sorry about that--I'm the one who started the thread. I've
contributed 
to some of the discussion over there as well.

Some of my anxieties may be simply derived from the fact
that I am not a 
select member of ADC, didn't attend WWDC, and have no
special knowledge 
that would be covered by NDA. Maybe 32-bit Carbon will be
supported 
forever and there's no need to worry. If so, great. But I
certainly 
*don't* see Tcl/Tk developers up in arms on any other OS
because the 
platform vendor has decided to forcibly migrate third-party
developers 
to its preferred API by deprecating the hell of out of the
crufty but 
long-running API that is the foundation of most established
commercial 
and cross-platform development on that system.
