I agree with you about fractories often being stupid replacements for free-functions. I am thinking of more dynamic things: e.g. a handle to a network connection should be passed around instead of singletoned. But even if dependency injection has all the costs you claim for it. Those costs are at their smallest when the system is small. So I still say xypud is wrong: you should do injection by default and when it gets too cumbersome then you think about how to streamline the interfaces.

To be honest...I have not thought hard on this. I expected my post to get down voted, as I figured i was taking a frowned upon view. To be more fair, I suspect I am wrong. In practice, I agree with your point. I'd rather do some small costs up front. I'm curious to explore the designs more. I think in systems where you have independent programs working together, a lot of this solves itself. The trend today is to make things one big program. (Not a new trend.)
