As for returned value, I propose to return -1 in case of error, 1 for yielded value and 0 for returned value (i.e. define PYGEN_RETURN = 0, PYGEN_YIELD = 1 and PYGEN_ERROR = -1, but without exposing public names).

It would be uniform with other C API: many functions return -1 on error (if they return int and can fail), and PyDict_Next() and _PySet_NextEntry() return 1 for every yielded item, and 0 if the iteration has been finished.
