I had to use this today. However, this does not work correctly when the set
is empty. We assume that if the set is empty, whatever variable value being
tested is not in the set.
Here's an updated __call__ function:
def __call__(self, value):
value, error = IS_IN_SET.__call__(self, value)
# if IS_IN_SET says value was in the set AND the set isn't empty
# then return an error
if error == None and len(self.theset) > 0:
return (value, self.error_message)
else:
return (value, None)
