-
-   An array of executable kinds (executor types) for frames, used for internal
-   debugging and tracing.
-
-   Tools like debuggers and profilers can use this to identify the type of execution
-   context associated with a frame (such as to filter out internal frames).
-   The entries are indexed by the following constants:
-
-   .. list-table::
-      :header-rows: 1
-      :widths: auto

-      * - Constant
-        - Description
-      * - .. c:macro:: PyUnstable_EXECUTABLE_KIND_SKIP
-        - The frame is internal (For example: inlined) and should be skipped by tools.
-      * - .. c:macro:: PyUnstable_EXECUTABLE_KIND_PY_FUNCTION
-        - The frame corresponds to a standard Python function.
-      * - .. c:macro:: PyUnstable_EXECUTABLE_KIND_BUILTIN_FUNCTION
-        - The frame corresponds to a function defined in native code.
-      * - .. c:macro:: PyUnstable_EXECUTABLE_KIND_METHOD_DESCRIPTOR
-        - The frame corresponds to a method on a class instance.
-
-   Note that reading the executable kind from a frame is currently only
-   possible with undocumented internal APIs.
