@deffn Command unknown-inputs
Print all nodes with value X that have no fanins, i.e. input-only nodes.  
Connections to channel sinks or sources can count as inputs (fake fanin).
Great for debugging forgotten environment inputs and connections!
This variant includes X-nodes with no fanouts (unused nodes).
