Use `acquireAndGet` (since we're not using the `Either` return type of `acquireFor`) as in the example on the [usage page](http://jsuereth.com/scala-arm/usage.html)?
```
managed(ContextBuilder.newBuilder("filesystem").overrides(properties).buildView(classOf[BlobStoreContext])) acquireAndGet {
  context =>
  ...
}
```
