# ui_mounted.ludic - an editor's questions of a running interface: which components the last frame
# showed (in tree order, each once) and one's model, read in place. App shows two Counters: the list
# is App then Counter, a Counter has a model, and a class not shown has none. Prints `App|Counter| 1 1`.
