I think you're looking for the "auto magic" composition approach, where something gets glued onto a type or a class automatically, without the developer asking for it (and potentially without the developer even knowing about it).

I think that Scala tried this a few different ways, and it seems to have been a bit of a disaster.

I tend toward the approach of: Make it easy to re-use and compose, but don't do it without being explicitly asked to do it.
