This is a guideline to give the standard way of implementing a new-style function in Chainer. Different developers can align the coding style by writing implementations based on this document.
A new-style function implementation consists of at least two elements:
an implementation of FunctionNode and a user interface function.
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.
