Good point. Just to make a note about $v1... it is relatively new. If you want your script to be compatible with versions older than 6.14 (I think $v1 was added somewhere around then, though it may be a different version), then you wouldn't want to use $v1. It's up to you how compatible you'd like it to be. Most people use 6.14 or higher, so it shouldn't be an issue for the majority of users. I just thought I'd point it out so you don't wonder why it won't work for someone.
