Why should they be handled at all?  If the programmer writes

    def __init__(a, @b, @c=[]):
        pass

then all instances that didn't have `c` given will share the same list -- just 
like if the code was:

    def __init__(a, b, c=[]):
        self.b = b
        self.c = c

The purpose of the syntax is to automatically save arguments to same-named 
attributes, not to perform any other magic.
