Macros should be protected from weird things (such as calling within other
macros) by forcing them to be evaluated.

#define RETAIN(obj)             [(obj) retain]
#define RELEASE(obj)            [(obj) release]
#define AUTORELEASE(obj)        [(obj) autorelease]

Other than that, it should be fine.
