-/* Starting in CPython 3.11, CPython separates the frame state between the
- * full frame objects exposed by the Python and C runtime state introspection
- * APIs, and internal lighter weight interpreter frames, which are simple C
- * structures owned by either the interpreter eval loop (while executing
- * ordinary functions), by a generator or coroutine object (for frames that
- * are able to be suspended), or by their corresponding full frame object (if
- * a state instrospection API has been invoked and the full frame object has
- * taken responsibility for the lifecycle of the interpreter frame).
- *
- * This split storage eliminates a lot of allocation and deallocation of full
- * Python objects during code execution, providing a significant speed gain
- * over the previous approach of using full Python objects for both
- * introspection and code execution.
- *
- * Struct names:
- *
- *   * PyFrameObject: the full Python frame object
- *   * _PyInterpreterFrame: the lightweight frame struct used by the eval loop
- *   * _PyCFrame: a struct that lives on the C stack and allows Python level
- *     recursive evaluation to be decoupled from recursive C level invocation
- *     of the bytecode eval loop
- *       * See pystate.h for more details on this struct
- *
- * Field naming conventions:
- *
- *   * full frame object fields have an "f_*" (or "_f_*") prefix
- *   * new interpreter frame fields have no prefix
- *   * Several interpreter frame fields have the "f_*" prefix as a result of
- *     trying to keep diffs as small as was feasible when splitting the original
- *     frame struct definition in two. The following are all interpreter frame
- *     fields, NOT full frame object fields:
- *     * f_func
- *     * f_globals
- *     * f_builtins
- *     * f_locals
- *     * f_code
- *     * f_lasti
- *     * f_state
- *   * Renaming those fields was considered but ultimately deemed too disruptive
- *     to key third party projects that were trying to keep up with the Python
- *     3.11 code evaluation changes during the alpha release cycle
- *     (see bpo-44800 for details)
- *
- * Naming conventions for local variables, function parameters and fields in other structs:
- *
- *   * "frame" and "f" may refer to either full frame objects or interpreter frames
- *     * the context of use or the field naming conventions usually make the
- *       type being referenced unambiguous in code reviews
- *   * the following alternative names are used when more clarity is needed:
- *     * full frame objects: "frame_obj" (and variants like "frameobj" or "fobj")
- *     * interpreter frame structs: "frame_data" or "iframe"
- *   * "current frame" should NOT be abbreviated as "cframe", as the latter now
- *     typically refers to _PyCFrame structs
- *
- * Function/macro parameter types:
- *
- *   * "PyFrame_*" functions and other public C API functions that relate to
- *     frames accept full frame object pointers
- *   * "_PyFrame_*" functions and other private C API functions that relate to
- *     frames accept either full frame object or interpreter frame pointers.
- *     Check the specific function signatures for details.
- *
- * Function return types:
- *
- *   * Public C API functions will only ever return full frame object pointers
- *   * Private C API functions with an underscore prefix may return interpreter
- *     frame pointers instead. Check the specific function signatures for details.
