We only allow *Ts if the argument is of the form *a. `def f(x: *Ts1)` is not allowed. Maybe you were thinking of `def f(x: Array[*Ts1], y: Array[*Ts2]) as the example? That seems unambiguous since the two positional arguments are given separately. -- --Guido van Rossum (python.org/~guido) *Pronouns: he/him **(why is my pronoun here?)* <http://feministing.com/2015/02/03/how-using-they-as-a-singular-pronoun-can-change-the-world/>
