`conn` is a magic argument isn't it? Like an implicit argument to this block of code? That is one thing that really bugs me, is I can't automatically see where the arguments are coming from. I realize it makes code a little more verbose, but a requirement around explicitly showing the dependencies used is much more useful when you're refactoring, for instance, or scaling code. not a hard requirement by any means, sure, and it definitely doesn't mean something won't scale as it were, however I am constantly frustrated by languages that allow for implicit scoped dependencies / arguments.
