For example, if you had foo(point) and much later you want to add
foo(box), someone might complain that foo('(1,2)') has worked for many
releases now, and how common is that use? If we had started out with
foo(point) and foo(line) simultaneously, this wouldn't have become a
problem.
You may provide foo(TEXT) along foo(box) so that foo('(1,2)') works as it
did before.
