At http://stackoverflow.com/questions/2633447/why-doesnt-perl-file-glob-work-outside-of-a-loop-in-scalar-context/2634012#2634012 I used a similar trick of creating closures to encapsulate the state of a glob operator, so that it can be used outside of a single while loop. This is slightly useless (since you can just glob to a list instead) but at the same time it's pretty cool.
