Not sure I see the problem. The typing overhead in the source should be
the same as in the macro approach, except that it can be automated a bit
more..
But in this light the macro change if expanding to something like the
above is in fact a step forward, unifying the code and making the
refcount transition easier.
In fact this reminds me of the cbdata macros..
   pointer = cbdataReference(original_pointer);
   cbdataReferenceDone(pointer);
where cbdataReferenceDone is essentially the if block quoted above, plus
some cosmetics for debugging purposes.
