It does conflict with the straw man syntax described in the generics manifesto:

	https://github.com/apple/swift/blob/master/docs/GenericsManifesto.md#variadic-generics <https://github.com/apple/swift/blob/master/docs/GenericsManifesto.md#variadic-generics>

but variadic generics are a long way off and the syntax is totally up in the air.
