[docs] [issue12955] urllib2.build_opener().open() is not friendly to "with ... as:"

New submission from Valery Khamenya <khamenya at gmail.com>:

The following intuitive construction

with urllib2.build_opener().open() as:
    ...

leads to AttributeError: addinfourl instance has no attribute '__exit__'

http://docs.python.org/library/urllib2.html says almost nothing about concept of closing.

Could it be possible to add a canonical "with ... as:" example for urllib2.build_opener() ?

Thanks,
Valery
