1. for "missing?" we often need to query database to check if an item exists. If predicates are truly independent, we will need to do the query again to return the item.
2. "data flow" looks something like this (in Prismatic's Graph lib):

(def stats-graph
  {:n  (fnk [xs]   (count xs))
   :m  (fnk [xs n] (/ (sum identity xs) n))
   :m2 (fnk [xs n] (/ (sum #(* % %) xs) n))
   :v  (fnk [m m2] (- m2 (* m m)))})

1) Use build_flymake.sh to compile flymake.erl into the eflymake script.
2) Replace your existing eflymake script with the newly built one.

NOTE: Don't forget to make a back up copy of your original eflymake in case this one has bugs!
