What is a concise way to implement nested disposers? Picture a typical resource returned by a method getResource that has a disposer, that you would use like this: getResource Promise.using( getResource(), resource => doStuffWith(resource)) .then( // "resource" is cleaned up by now ) Now imagine another method wrapResource that took the resource as an argument and returned it decorated in some way (perhaps adding its own initialize/teardown steps) - perhaps with its own disposer. You could use such a method like this: wrapResource Promise.using( getResource(), baseResource => Promise.using( wrapResource(baseResource), resource => doStuffWith(resource))) My question is whether there is a way to write the above in a more succinct way that abstracts away the wrapping of that resource, something you could use like this: Promise.using( getWrappedResource(), resource => doStuffWith(resource)) In other words - how could ...
