Generator Objects
-----------------
Generator objects are what Python uses to implement generator iterators. They
are normally created by iterating over a function that yields values, rather
than explicitly calling :cfunc:`PyGen_New`.
.. ctype:: PyGenObject
The C structure used for generator objects.
.. cvar:: PyTypeObject PyGen_Type
The type object corresponding to generator objects
.. cfunction:: int PyGen_Check(ob)
Return true if *ob* is a generator object; *ob* must not be *NULL*.
.. cfunction:: int PyGen_CheckExact(ob)
Return true if *ob*'s type is *PyGen_Type* is a generator object; *ob* must not
be *NULL*.
.. cfunction:: PyObject* PyGen_New(PyFrameObject *frame)
Create and return a new generator object based on the *frame* object. A
reference to *frame* is stolen by this function. The parameter must not be
*NULL*.
