You define a new type with tp_flags including Py_TPFLAGS_HAVE_ITER.
Anything that would be a local variable in your generator needs to become
an attribute in the type.
The tp_init initialization function should contain all the code up to the
first yield, tp_iter should return self and tp_iternext should execute code
up to the next yield.
