gocty: Too inflexible about map vs. object distinction about go-cty

[apparentlymart]

Hi @doctornkz,

If you want to have a sequence where each element has its own type, I think tuple types are what you are looking for. You can use a tuple type instead of a list type to track each element value separately.

I am not sure it's connected with topic, but I have problem with cty.Maps and cty.Objects, please point me if I'm wrong.
I need to create the structure - List of Maps. [{},{},...].
Obviously, I should to use cty.ListVal around ctyMapVal.
As example:

func main() {
	myMap := cty.MapVal(map[string]cty.Value{
		"test":  cty.NumberIntVal(1),
		"test3": cty.StringVal("test3"),
	})
	myMap2 := cty.MapVal(map[string]cty.Value{
		"test1": cty.NumberIntVal(1),
		"test2": cty.StringVal("test6"),
	})
	var rows []cty.Value
	rows = append(rows, myMap)
	rows = append(rows, myMap2)
	myList := cty.ListVal(rows)
	fmt.Printf("%v", myList)
}

I receive error:

panic: inconsistent map element types (cty.Number then cty.String)

Ok, unconsistent map fields/keys ! I need to use cty.Object, cos it have flexible types!

		myMap := cty.ObjectVal(map[string]cty.Value{
			"test":  cty.NumberIntVal(1),
			"test3": cty.StringVal("test3"),
		})
		myMap2 := cty.ObjectVal(map[string]cty.Value{
			"test1": cty.NumberIntVal(1),
			"test2": cty.StringVal("test6"),
		})
		var rows []cty.Value
		rows = append(rows, myMap)
		rows = append(rows, myMap2)
		myList := cty.ListVal(rows)
		///fmt.Printf("%v", myList)

But it also doesn't work for me:

panic: inconsistent list element types (cty.Object(map[string]cty.Type{"test3":cty.String, "test":cty.Number}) then cty.Object(map[string]cty.Type{"test1":cty.Number, "test2":cty.String}))

because ctyList wants to keep the equal structures in container. It's OK, it's golang way. But in Golang we have interface{} to create list of any types. What is the correct way for cty here?
