Proposal: Moratorium on Python language changes

You can can get in and out of "with" blocks repeatedly with the same context manager instance. Locking and all kinds of transactions are a good example, I'd be surprised if those are not mentioned in a PEP for "with." As for less conventional stuff... I used it once to control output indentation level in a console tool. A primitive bug tracker web application wrapper I wrote for work must use SOAP so suds (https://fedorahosted.org/suds/) is my friend. I'd rather not keep recreating all the SOAP metadata, so I keep the same suds SOAP "factory" inside the wrapper class and use context manager pattern to log into/out of the bug tracker.
