David: Your example tests specifically for a string, but what about just 
converting default to a string always if it's not a list?  Otherwise the string 
join is just going to fail anyway (suppose an integer is passed, which is the 
case with couchdb-python).  Wouldn't


if not isinstance(default, list):
    default = [str(default)]

Be safer?
