Extending a struct with generic array type specification

Question

Is it possible to do something like this at all in swift 4?

extension MyStruct where T: [Object] { }

I thought there has to be a way as this compiles:

let property = MyStruct<[Object]>()

My struct would than look like this:

struct MyStruct<T> { }

You want to restrict T to be equal to some type:

extension MyStruct where T == [Object] {

}

A constraint T: P would be used to restrict T to conform to (or inherit from) P.
