That's pretty much sums it up. We do use mixins and they serve an important part in our app, but we are often hindered by the fact that mixin candidates must be a direct subclass of Object. Precisely speaking, these 2 issues bugs me the most:

Mixin is of the great parts of Dart, and I think it's even under-promoted. But I also really hope we can see Gilad's spec coming true sooner.
