 English for one, see my example for ``present'' in the post just above.
 
 The Knuth & Plass paper which I cited has a formal proof and discussion of the impossibility of  finding the perfect set of breaks for a paragraph.
 
 jbjb --- you keep saying that something is possible (machine-done, perfect page composition) and asking people to prove that it's not possible --- yet you can't prove that it is possible by showing us a single implementation --- yet a large number of people, some of whom work in this field are stating that it isn't possible, and have pointed you to research papers on the difficulties of this task.
 
 I can't even find a grammar checker which can reliably disambiguate between the two different forms of ``present'', let alone every other such word in the English language --- and that's only a small part of the problem.
