Bug report

The following code gives me an error:

fromtypingimportGeneric,TypeVarTuple,ParamSpecTs=TypeVarTuple("Ts")P=ParamSpec("P")classFoo(Generic[*Ts,P]):passFoo[int,str, [bytes]]

TypeError: Too many arguments for <class 'Foo'>; actual 3, expected 2

I don't see any reasons why it doesn't work withParamSpec. I believe it should assignint, str toTs and[bytes] toP.
