It could aimed at list1 + list2 + list3. Or foo() + list2, where foo() returns a new list. Or other examples when the left operand is a new object. But it is not correct to say that it is a problem that currently these operations has quadratic complexity. They have the complexity O(N^2) where N is the number of additions. Unless you have expressions with many thousands of additions, this is not a trouble (actually you can get a crash in the attempt to compile such expression in CPython). |
