I'd be really curious about techniques that permit mutation during the construction of functional datastructures; this seems like a cool way to get fast performance w/o giving up any of the benefits of immutability. Unfortunately, my (admittedly short) experiments in this domain ran up against the difficulty that vector didn't let me unsafely freeze its mutable version. :-)
actually, this technique is already used in haskell. look into array library sources, search for freeze -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
