[Python] enabling the `with` statement?

[Phillip B Oldham <ph...@gmail.com>]

Are there plans to enable use of the python `with` statement?

For example, it would be useful to be able to do something like the
following (server implementation):

with MyThriftObject.containedObject as obj:
    myvariable = obj.foo
    # do something here

or:

obj = MyThriftObject()
obj.containedObjects = []
for my_dict in my_list_of_dicts:
    with ContainedObject() as c:
        # map my_dict to c here
        obj.containedObjects.append(c)

Currently python throws errors such as:
  AttributeError: 'MyThriftObject' object has no attribute '__exit__'

Just use a local variable for obj or c.  It looks like you are
trying to use Visual Basic's "with" statement.  Python's is closer to
C#'s "using".
