Review Comment:
Yeah that's one of my questions - do we need a symmetric implementation
between scala and python? Or we just need API to match. I have not had the
chance to look at the scala implementation.
On the other hand, is this mixin public? That users can use directly? If so,
merging this means we have to go with this method in the future right? To keep
compatibility.
