In which case the code becomes brittle, because you have to remember to
decref the partial result (if any), and every temp, before returning.  It's
not especially hard to get that right when you first write the code, but
under modification the number of error returns increases, and the set of
temps changes, and exactly when each temp first becomes non-NULL shifts, and
then you've got an ever-growing number of code regions that need to be
patched by hand.  The goto version remains dead simple.
