approaches like opening within the dump or load, which the wiki still recommends [1].

So something like:

with open('myfile.p', 'wb') as f: pickle.dump(myobj, f)

Would be:

pickle.dump(myobj, 'myfile.p')

What if you could write pickle.dump(myobj, with open('myfile.p', 'wb'))?

Or other similar examples such as (with open('myfile')).read() - have the compiler automatically transform the code into equivalent to wrapping the statement in a with block.
