Not stone, just molasses. If you learn bgen and submit proper patches,
you can fix existing modules in the 2.4 maintenance branch and add/or
features to the 2.5 branch.

You can learn bgen and fix it the correct way, and submit a patch.
Jack doesn't need to commit the patch. I did this once or twice, it's
possible for someone other than Jack to do it.
You're confusing issues here. The problem is that you need OSA
functionality. Removing something from the standard library does
nothing to solve that problem.
Removing the extension may or may not be a good idea. If /some/ of it
works, it might be worth keeping.

FSSpec is legacy. It should not ever be used in any code except to
reference nonexistent files or to deal with legacy APIs. You shouldn't
use them if the API will take an FSRef or an Alias. In this case, the
API *asks* for an Alias. So, yeah, you do actually want an Alias.

It can't happen until Python 2.6 at the earliest. I don't think it's
very likely to go away anyway. Good luck!
My point is that it's perfectly fine to IGNORE THE STANDARD LIBRARY.
Whether or not the Carbon package exists in the standard library has no
effect whatsoever on a "MacAll" package! The only harm it's doing is
taking up the name 'Carbon' in the sys.modules namespace. For
compatibility reasons, the MacAll package can't use the name Carbon
