BTW, re-invented at least as often is a VISIT macro for use in tptraverse slots, like typeobject.c's (and several other files')

_#define VISIT(SLOT) _ _if (SLOT) { _ _err = visit((PyObject *)(SLOT), arg); _ _if (err) _ _return err; _ } Shouldn't this also be wrapped in a do {} while (0)?

I think it's obvious that this macro has not been made generic yet, given that err, visit, and arg aren't defined anywhere.
