That's interesting, but you can get the same effect with a function
attribute, if you really don't want to write a class... that way also
protects you against accidentally passing something in to override the
default. (Incidentally: I feel that the "lambda x = x: ..." idiom to avoid
multiple closures sharing state is an ugly hack, for the same reason.)
