Redux-persist: "Unexpected token in" from Flow

[gausie]

I get the following Flow errors on a project for which I have redux-persist installed.

Error: node_modules/redux-persist/es/index.js.flow:53
 53: declare function createTransform(in: Transformer, out: Transformer, config?: TransformConfig): Transform
                                      ^^ Unexpected token in

Error: node_modules/redux-persist/lib/index.js.flow:53
 53: declare function createTransform(in: Transformer, out: Transformer, config?: TransformConfig): Transform
                                      ^^ Unexpected token in

I assume this is because in is a reserved word

this has been fixed in 5.3.4 👍

Any chance we can get a fix for that in v4?
