I was hoping for a generalized, simple idiom for this, rather than needing to implement it myself, for demonstration purposes (and for easy reuse later, of course). Your solution does not exactly fit my preferences for simplicity, but I might include it in an article I'm writing anyway. It's simple and readable enough that it should not clutter up the article much. I tested it for some simple use cases, and it works well. Thanks for saving me a little trouble. -- Chad Perrin [ original content licensed OWL: http://owl.apotheon.org ]
