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 one implement getWrappedResource?
