Conciseness? I guess it's debatable whether constants with non-infinite rank are more or less common than gerunds which need to conform to the shape of their (eventual) verb argument.
Perhaps it would be worthwhile collecting useful examples of each? I know I've used low-rank constants within the last few years, but at the moment I do not remember where...
