The question is what we need. Maybe not some exotic corner cases.
IMHO, they are mainly used as callbacks from asynchronous activities
(networking).
In ObjC1 this was handled by delegates or blocking and passing back complete
results instead of callbacks.
It looks like the key aspect is to get new block based method names in header
files (almost) compatible.
Well, we never can automatically replace ^ by something in application code by
a cpp macro.
