I made a stupid mistake, and I want to share. This is not the actual code, I simplify it to demonstrate the point.
I use a atom to a global hash as follow: (def *aa* (atom {:x 3 :y 4 :z 17})) Somewhere on the code, I have a function which look at the state and do something: (defn foo [state] (when (:x state) print "yes")) My mistake - call foo as: (foo *aa*) where I should have call it (foo @*aa*) Since (:x (atom *aa*)) is nil, print was not execute. 4 long hours later, I got it, fix it, and added the appropriate precondition. I understand there is no escape from my own silliness, but could I have avoided this mistake to begin with? Any best practice I broke?
