CAD is a stronger example (once you get to any practical complexity, naming the entities becomes intractable (and you need names to form text sentences about them), spacial selection is much more effective, even with hierarchical grouping of parts.) Though even for text-based development, it's worth looking at Bret Victor's "inventing on principle" talks - it's more about the discrete vs continuous boundary (and that more things are honestly continuous than you might assume.)
