Yes, the new version is SO much easier on the eyes.  Eliminating the 
extra continuation not only makes it easier to read, but a bit faster as 
well.  The other simplification is that the original version supported 
delayed choices, i.e. passing in a lambda as a choice where that lambda 
wouldn't get evaluated until the choice was needed.  Although a cool 
idea, I don't think I ever used it in any of the puzzles.  So, it was 
extra baggage that wasn't really needed.
