No, the problem is not when the function is called, but when value is bound into the closure. > I'd use a closure rather than a lambda. The original solution does use a closure. The problem is that variables are not bound into a closure until the scope of the variable exits. That is why using a separate factory function works - the closure is bound when the factory function exits which happens each time through the loop. In the case of closures in a loop the closure is not bound until exiting the scope containing the loop and all the closures are bound to the same value.
