Some made a python recipe emulating this I believe.  The python cookbook 
search engine is down though so I cannot find the link.
At one point Guido van Rossum was advocating this use of "with" as well, 
I believe: 
http://mail.python.org/pipermail/python-dev/2004-March/043545.html

But I don't think it is being considered now.  I think now "with" is 
being proposed for something more like VB and C#'s "using" statement. 
It automatically disposes of a resource when done with it:
