These aren't established practices yet. There don't seem to be any. This is not serious criticism, as I'm sure practices will evolve, but I think that currently it is a deficiency in the Clojure ecosystem. Making namespaces more like modules (that can be instantiated and parametrized) might help at the language level.

I'd agree with namespaces-as-modules, it's something that'd make program composition a lot nicer in my opinion.
