+TaskGroup can be created using ``@task_group`` decorator, it takes one
mandatory argument ``group_id`` which is same as constructor of TaskGroup
class, if not given it copies function name as ``group_id``. It works exactly
same as creating TaskGroup using context manager ``with TaskGroup('groupid') as
section:``.
Review comment:
It's not mandatory if it works out a default ;)
