Report from the Rabbit Warren.
Thank you, everybody, for your contribution. The problem was, how to construct a one-liner which generates the infinite Rabbit Sequence: 10110101101101011010110110101101101011010110110101101011011010110... This is the result of an *infinite time* evolution of a system which iteratively rewrites one young rabbit: 0 -> 1, an old one, and one old: 1 -> 10: itself and a young offspring. The finite sequence after n units of time fulfils: rs n = rs (n-1) ++ rs (n-2).
And now we have much Haskell code for one sequence to be submitted to the Online Encyclopedia of Integer Sequences!
