IndexedAssignExpr is a subclass of ShortcutExpr used in situations like x[y] += z where we need keep of two extra scratch variables and the get's matching set method. Note this class models the top x[y] += z, NOT the get target which is x[y].

In this example, IndexedAssignExpr shortcuts Int.plus and its target shortcuts List.get:

x := [2]
x[0] += 3
