Kristján Valur Jónsson added the comment:
These macros work as assignment with builtin decref,
i.e. a smart replacement for =
We could resolve this by calling them Py_ASSIGN Py_XASSIGN
and having complementary macros Py_STORE/Py_XSTORE that will incref the new value.
However, with an added incref, does the X apply to the source or the target?
I wonder if we need the X variants in these macros. Once you are doing things like this, why not just use X implicitly? An extra pointer test or two is unlikely to be a performance problem in the places you might use them.
Anyway, I'll be adding this to the internal api of stackless because it is tremendously useful.
