Thanks Roger! I had written something fairly similar already. I really wish there was some validator decorator that would coerce the values into lists for me. Likewise, I wish the kwargs object was a special dictionary that supported a "get_as_list" method.
IMHO, the python world should rethink making strings iterable. I would prefer that you had to cast a string into some "iterable string" type before iterating across it. I have been bitten more times than I can count by forgetting to check the type of my object and then iterating across some string rather than a list of strings.
