I was about to complain about this next, as soon as I got the previous part working :-) > If we had some light primitives for this, that GHC new about (head#, > length#), that accessed the internal data about what strings are up to, > that could be useful. If we had the two simplification rules I suggested, and RULES, I think you can write length# yourself. Of course, its not necessarily going to be pleasant, and may require N rules iterations, where N is the length of the string.
