@dan-zheng wrote a document on our current design and implementation of KeyPathIterable and its conformances synthesis.

KeyPathIterable is released as part of Swift for TensorFlow v0.2, and is one of the core building blocks of the Swift for TensorFlow Deep Learning Library.

## Background and motivation

The ability to iterate over the properties of a type is a powerful reflection
technique. It enables algorithms that can abstract over types with arbitrary
