Internally, structures are represented by an object that can be treated either
as an array or dictionary. When you're getting a structure into your plugin,
you shouldn't rely on it being one or the other, however it looks like we could
do something better when the structure does have keys. Writing a writing a bug
to make sure that it outputs as a dictionary if it has keys would be helpful to
us.
