Nick Coghlan <ncogh...@gmail.com> added the comment:
One thing that Jack's confusion above does suggest to me is that we should
mention in the *ContextDecorator* documentation that it is automatically
applied to the context managers created when you use @contextmanager. A lot of
people familiar with contextmanager are just going to read the docs for the new
toy, so may miss the fact that we have added __call__ support to
GeneratorContextManager.
As far as use cases go, this change is just syntactic sugar for any construct
of the following form:
def f():
with cm():
# Do stuff
ContextDecorator lets you instead write:
@cm
def f():
# Do stuff
It makes it clear that the CM applies to the whole function, rather than just a
piece of it (and saving an indentation level is nice, too).
