Hey, We've actually worked on this extensively in bluebird with http://bluebirdjs.com/docs/api/promise.using.html and disposers which give something similar to the `with` syntax you describe.
There has also been work on a `defer` like abstraction. The tricky parts were mostly getting it to work with multiple resources at once. I've been using it for a while now (few years) and I'm generally satisfied. Cheers, Benjamin
