> The philosophy of the TP3 API is "containers only when necessary". There is
> a tendency to eschew the container when its size would be one.
> For example, {{select("foo")}} will not emit a {{Map}} with a single
> key/value, but instead will emit a single value. Similarly, if any
> {{select}} of a step label finds only a single instance of that step in the
> path, it will emit the value at that step; only if multiple steps in the path
> have the same label will a {{List}} be created.
> In that spirit, {{limit(local, 1)}} should emit an element, rather than a
> one-element {{List}}.
> This would also mean that {{range(local)}} operating on a {{List}} would emit
> a single element if the number of elements is selected by the range is 1.
> This would also reconcile the behavior with the {{tail}} step.
