It would certainly be cleaner - we could do something similar in [`toFilesInResources`](https://github.com/jclouds/jclouds-cloud-storage-workshop/blob/deprecate-async/exercise2/src/main/java/org/jclouds/labs/blobstore/exercise2/MultiFileUploaderC.java#L131) but there's a lot about all these examples that would certainly be cleaned up for production code.

To me, these are simply "first cut" answers to a 10-15min coding exercise, and from that perspective I'd probably leave a next round of cleanup to the more comprehensive overall that'll be due for 2.0.

OK? Now to squashify once more...
