> There’s a brief window in the early morning after a small piece of chocolate where I think I understand the Holy Trait pattern. However, by afternoon, I’m back to puzzling… I know the problem exists. I’m not even sure I could describe the problem.

I wrote a little about the idea behind traits [here](https://discourse.julialang.org/t/how-to-subtype-a-type-alias/24050/4), not sure if that’s helpful. Maybe [this blogpost](https://invenia.github.io/blog/2019/11/06/julialang-features-part-2/) by @oxinabox is helpful.

The problem with explaining traits is that it’s really hard to find a small self contained example of why they’re useful. For any small snippet, defining a `supertype` is just better. Traits really become useful when you have multiple packages interacting that don’t want to all share a supertype, or in cases where you really want a type to have two supertypes.
