Would the following solve your usecase? Explicit naming:

    with myobject import a,b,c,d:
        a
        b
        c()
        d = 1


Alternatively, putting the object at the end (like in gen expressions):

    with a,b,c,d from myobject:
        a
        b
        c()
        d = 1


Questions:
    * Should this add additional scope?
    * Descriptors and `__getattr__`-only attributes: Do you get the
attribute at the start of the block, or do you call `__getattr__`
every time?
    * That `d = 1` is Pythonically odd if it works as in the original example.
