There's a performance benefit in using __iadd__ for the interface: slot methods are more quickly looked up than regular methods. Also, if A is immutable, then an explicit mutating operation would be uncalled for. If A is mutable then we can just implement __iadd__ without concern for reference counts. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
