To enable these extensions, set the TBB_PREVIEW_TASK_GROUP_EXTENSIONS macro to 1.
Description
oneAPI Threading Building Blocks (oneTBB) implementation extends the tbb::task_group specification with the requirements for a user-provided function object.

As an optimization hint, F might return a task_handle, which task object can be executed next.
NOTE:
The task_handle returned by the function must be created using *thistask_group. That is, the one for which the run method is called, otherwise it is undefined behavior.

template<typenameF>voidrun(F&&f)
As an optimization hint, F might return a task_handle, which task object can be executed next.
NOTE:
The task_handle returned by the function must be created with *thistask_group. It means, with the one for which run method is called, otherwise it is an undefined behavior.
