Python standard lib : give me more withs !

I used to write in files like this :
open('somefile', 'w').write(content)

It's ugly for sure, and a more proper way is :
f = open('somefile', 'w')





But since Python 2.6, the with statement is superior for this code pattern:
with open('somefile', 'w') as f:


This is so natural in fact that I am always thinking about with when I work with classes that have a start/stop or open/close behavior.

So, what about adding this behavior into imaplib.IMAP4, ftplib.FTP and smtplib.SMTP ?

So we can write things like this :
>>> from ftplib import FTP

    >>> with FTP('') as ftp:

    ...     ftp.login('someone', 'pass')

    ...     (some code)


I am working on a series of patches for this, and wondering if some other classes in the standard library could benefit from this as well..
