[Jeremy Bettis]

And why not just
#define TEST_AUTORELEASE(object) [object autorelease]

Since methods sent to nil are really not a bad thing.

Oh sure in the case where the object is nil you have a function call where
you could have gotten away with just a branch instruction, but the
objc_send_msg is going to check for nil again anyway.
