Pretty certain???  That doesn't inspire confidence <wink>. How certain are
you that this will be true in the future?

I think it bad style indeed - for example, I could see benefit in having
DECREF (or _Py_Dealloc, called by decref) set the object to NULL in debug
builds.  What if that decision is taken in the future?

I thought rules were pretty clear with reference counting - dont assume
_anything_ about the object unless you hold a reference (or are damn sure
someone else does!)

Mark.
