[cfe-dev] Flexible array members in ObjC classes

[Nat! via cfe-dev]

My initial reaction was, a flexible array as an ivar is dumb. Flexible 
array ivars must appear at the end of the struct (AFAIK). Then you can't 
subclass such a class anymore.

My second reaction, was to think that there are class cluster classes 
with allocate a flexible amount of memory (say string classes) that 
aren't ususally subclassed. Who am I to say, that using a convenient 
flexible array there can't be done (anymore) ?

I would think a warning would be nice for classes who try to subclass a 
class with a flexible array ivar if they add another property or ivar.
