John Mackin, in an aside, asked me whether i could find a use for rc's current pairwise concatenation; except for a few contrived examples, i can't think of a reasonable way to use it. i've talked to Byron about this a little, and a couple of other people, and no one has come up with a good use for it. [ i don't mean concatenation of a 1 element list with an n element list, i mean an n element list with a n element list. ] therefore, i am offering a small prize to the first person who comes up with a NON-CONTRIVED example of using pairwise concatenation. by contrived i mean something that somebody would not do except to use this feature of rc. i would most like an example that has actually been used before this message was sent out, but one that you come up with explicitly to answer my question is fine. the prize: one (real, official, shrink-wrapped) font package of your choice from the adobe type library. retail price of these things is typically US$ 150-300. if you don't care about fonts, maybe i can hunt something else up. the deadline: August 20th, 23:59:59 PDT. (that's two weeks or so from now. should be enough time.) send entries to: haahr@adobe.com or ...!decwrl!adobe!haahr the judges: me and Byron. we have the right to be completely arbitrary. we'll also post all entries to the net after the contest is over. if you don't want your name associated with your suggestions, say so.
