As the ?: ternary operator is already an expression,

#define TEST_AUTORELEASE(object) \
       ( object != nil ? [object autorelease] : nil )

would do, but surely to avoid the possible side-effects
in the macro argument(e.g.):

TEST_AUTORELEASE([foo gimmeAnotherObject])

#define TEST_AUTORELEASE(object) \
       ({ id o = (object); (o != nil) ? [o autorelease] : nil; })

would be safest of all
