Retrieving the root value

[aeneasr]

The JSON Pointer specification allows to retrieve the root value of a JSON document using the pointer #/. I was unable to figure out how to do that with GJSON paths. Is this currently possible?

I've tried several approaches but was unable to get the root element (I know that this is jj and not gjson but since one uses the other I assume that the inputs would return the same output for gjson too):

% echo '{"name":{"first":"Tom","last":"Smith"}}' | jj '.'

% echo '{"name":{"first":"Tom","last":"Smith"}}' | jj '' 

% echo '{"name":{"first":"Tom","last":"Smith"}}' | jj '*'     
{"first":"Tom","last":"Smith"}

I was unable to figure this out using the docs, but maybe I missed it.
