Given pseudo-code (Ruby-ish):
due = 100
cards = cards.map do |card|
card.applied_balance = max(0, due - card.balance)
due -= card.applied_balance
Notice how due changes at each turn, and each successive item in
"cards" sees the change.
What's an idiomatic way to do this in Clojure without using refs?

Not a Ruby expert here, but I think 'reduce' is your friend.... :)
loop/recur is also an option ...
the problem is not really how to loop, but how to replace all this
mutation...I'm saying this because you specifically asked not to use any
reference types.
