I was looking for a reference for the addition of multiple context manager support to with statements in 3.1 and 2.7 and came up empty (aside from the initial python-ideas thread [1] that I linked to from PEP 377). I was hoping to find something that clearly spelled out: - the two major flaws in contextlib.nested* - the parallel with import statements for the precise chosen syntax - Guido's blessing to go ahead and do it *Those flaws being - that __init__/__new__ methods of inner context managers aren't covered by outer context managers - that outer context managers can't suppress exceptions from inner __enter__ methods Note that I'm not complaining about the decision itself (that would be silly, since I agree with the outcome), I'm just trying to find something to point to about it that is a little more concrete than a python-ideas thread. Cheers, Nick.
