Unrelated note: drop the &. It's not necessary in this case and means something else than people tend to think in other cases.
Could you explain this or give a reference. I see this comment a lot, and have never experienced any side-effect of using the '&'. I use the '&' to visually distinguish between in-script 'sub's and 'sub's that I have no control over via use/require/Begin.
When you haven't looked at code in 2-5 years and now need to modify it, small visual aids do help!
