Thrush in Clojure

Isn't he looping many times in this example. In an imperative language I would loop through the records once, find savings accounts, get balance and add to total - all in one loop.

The point of the article was likely only this Thrush feature, and not the problem of implementing accounting systems.

For a small list like this I would use a fold function and accumulate up savings account amounts, all in one pass, all functional.

Dont think so-- Clojure's map and filter return lazy sequences, so this code likely only iterates once (in the +).
