title: Overload () operator in Python
body: <p>I am trying to learn currying in Python for my class and I have to overload the () operator for it. However, I do not understand how can I can go about overloading the () operator. Can you explain the logic behind overloading the parentheses? Should I overload first ( and then ) or can I do any of these? Also, is there special name for parentheses operator?</p>
