"Martin v. Löwis"
You seem to think that the problem has an obvious solution, which is not true;
But is *has* an obvious solution. See the implementation from Dj Gilcrease, or the spec that I just posted.
Two different solutions are both obvious? There are other solutions
proposed elsewhere too; are they also obvious?

Quite possibly; I'm not intending to impose my position on anyone. I'll go back to lurking on the thread for a while and see if it becomes any clearer. -- \ “First things first, but not necessarily in that order.” —The | `\ Doctor, _Doctor Who_ | _o__) | Ben Finney
