Hi, dotrace is used to trace fns by rebinding their vars and providing a list of expressions to be traces in a restricted scope.
Like this: (dotrace [my-add] (my-add 4 6) (my-add 7 3)) I played with it but now it's pretty useless because how vars are handled in 1.4. Not even sure if it works in 1.3. If you do not need such restricted trace scope, why not use (trace (my-add 10 2)) ? Or deftrace instead of defn ? If you need to dynamically enable/disable tracing of fns, use trace-vars/ trace-vars. You will find a usage example in the readme. In the next release I will change dotrace so it will work again.
