What is the status about this extension ?
It is unlikely that this will ever be brought into GCC, since
it appears to be largely identical to the C++0x Lambda feature.

I agree that it is superfluous for C++ at this stage but it might be
nice for Objective-C (regular C) although Objective-C++ will then have
to be taught how to deal with it somehow anyway.
OTOH, with lambdas it might be more easy to put this in.* It is
probably just a special case of lambdas. We'd have to find out which
one of course. I think syntactically it shouldn't be too bad.**
In general, and this has come up before, there are other things in
Objective-C 2.0 that we don't have. IIRC the Apple trees left behind
are a little old and not in good shape. What are the licensing issues
for borrowing from LLVM leaving aside the technical issues?

* Or not. I think C++ lambdas are implemented as a little class of some
type which might make C mad.
** I was noticing that C++ lambdas and Obj-C message passing syntax
collides a little.
