I wasn't clear about that either. The idea is:
def add(new_value):
if not values_array:
if self.magic_value is NULL:
self.magic_value = new_value
elif new_value is not self.magic_value:
self.values_array=[self.magic_value, new_value, ... ]
else:
# new_value is self.magic_value: do nothing
I am neutral on this proposal myself. I think that even if we optimize
any code where you pass the same thing over and over again, we should
document a convention for consistency. So I'm not sure there is much
advantage.
