Candidate API changes for Chainer v2

Candidate API changes for Chainer v2

In this gist, I list up the possible changes on existing APIs for Chainer v2. It also includes some ideas of adding new APIs related to existing ones. Note that this is not a complete list of future changes for v2.

New-Style Function Implementation Guideline

New-Style Function Implementation Guideline

Basics

A new-style function implementation consists of at least two elements: an implementation of FunctionNode and a user interface function.
