The idea that a parameter is optional, but doesn't have a value, may itself be worth exploring (maybe some way to say "arg=pass" and then have an operator "if unset arg:" that returns True if it's unbound), but that's for another day.
ChrisA Indeed. And it could be useful to know if a parameter was passed a value or given the default value. Python has very comprehensive introspection abilities, but this is a (small) gap.
