I'd want a 3D node editor interface much like Blender's texture or geometry creation interface. The nodes would be 3D objects (cubes, cylinders, etc) and nested groups of objects w/ physical ports that could be wired together.

Nodes would include class/object/method nodes w/ code blocks. So, an important AR/VR UX feature would be the ability to collapse/dive-into nodes & groups of nodes much like code-outliners in 2D IDEs.

Another awesome feature would be the ability to affix dials/gauges and other displays to the outside of nodes & node groups that would provide indicators of the unit's state: How "full" is a collection node, how often/frequently was this node invoked, the health of the node (errors, exceptions, slow-execution times), etc.
