But do you have one?

I understand that you want the context to make the decision, instead
of counting on a caller to do it properly.  But why can't you do that
with a decorator instead of a context?  I think your examples are
covered by http://wiki.python.org/moin/PythonDecoratorLibrary#Memoize

Is it just that you want the stuff inside both your function and your
context manager/decorator to have access to the same locals, and don't
want to use a closure and/or pass around a dict?
