For that example, what about just defining a 'walk method for every collection and defining 'each the way Anarki does?

  (mac each (var expr . body)
    `(walk ,expr (fn (,var) ,@body)))

"Each" can iterate over millions of elements; in this case, we can use class macros to remove the function calls.
