Hi,
I compiled a list of some possible new context managers that could be
added to the stdlib. Introducing a new feature should IMO also show
usage of it in the distribution itself. That wasn't done with
decorators (a decorators module is compiled at the moment, if I'm right),
but with context managers, there's certainly room to add some. Of course,
my list is excessive, it's only some ideas I got by flying over the stdlib
docs.
