Detailed Description

Establishes the given context as a StackContext that will be transferred.

Note that the parameter is a callable that returns a context
manager, not the context itself.  That is, where for a
non-transferable context manager you would say::

  with my_context():

StackContext takes the function itself rather than its result::

  with StackContext(my_context):

The result of ``with StackContext() as cb:`` is a deactivation
callback.  Run this callback when the StackContext is no longer
needed to ensure that it is not propagated any further (note that
deactivating a context does not affect any instances of that
context that are currently pending).  This is an advanced feature
and not necessary in most applications.
