Please remove/split struct or array[struct] definitions

[PennyJim]

There's times I want to annotate a function to only take/return the struct, not the array possibility. The definition for the type being tied to it, is annoying.

I'd much rather the places that use it hold the responsibility to do the type or array[struct] definition.
On the other hand, you can make a whole different type for it like StatelessVisualisations.

As I understand how the json format works, this would also optimize its size. While not that important, it's still a positive :]
(though the solution for size would be a special complex type)
