Thanks also Kevin for this feedback!
Good point about being careful to distinguish type parameters vs type arguments. If I understand correctly, you're making two points:
1. The wording of the 'Multiple Type Variable Tuples: Not Allowed' section - you're saying that we're being a bit imprecise here in saying that we disallow multiple TypeVarTuples in a type parameter list, given that in e.g. `def f(x: *Ts1, y: *Ts2)`, both Ts1 and Ts2 are members of the parameter list for the function f, but there it's unambiguous, so in fact it *is* allowed.
That looks like a syntax error. 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-c...>
