I'd be more amenable to a proposal along these lines (rather than
adding a parameter to closing), as it more closely resembles the way
that contextlib.ExitStack.callback already works:
with contextlib.ExitStack() as stack:
stack.callback(fn, *args, **kwds)
...
In cases where you just want to call a single operation and don't need
the extra complexity and overhead of the dynamic stack, then it would
be nice to be able to instead write:
with contextlib.callback(fn, *args, **kwds):
...
Cheers,
Nick.
