 We've found a bug for you!
  C:\code\src\git.cheung.nyc\kevin\firstRE\re\app.re

   7 Γöå   <Text style=Style.(style [color "#000"]) value="hello world" />
   8 Γöå   <Text style=Style.(style [color "#000"]) value=(string_of_int 10) />

   9 Γöå   <Test />
  10 Γöå   <Greeting name="John" />
  11 Γöå </View>;

  This is:
    name::'a =>
    ReasonReact.componentSpec
    int int ReasonReact.noRetainedProps ReasonReact.noRetainedProps
     Test.action
  But somewhere wanted:
    ReasonReact.component 'b 'c 'd (defined as
      ReasonReact.componentSpec 'b 'b 'c 'c 'd)

app.re

open ReactNative;

let app () =>
  <View>
    <Test />
  </View>;

test.re

open ReactNative;

type action =
  | Press;

let component = ReasonReact.reducerComponent "Test";

let make ::name _children => {
  ...component,
  initialState: fun () => 0,
  reducer: fun action state =>
    switch action {
    | Press => ReasonReact.Update (state + 1)
    },
  render: fun self =>
    <Button
      onPress=(self.reduce (fun _event => Press))
      title={j|Hello. You've clicked the button $self.state times(s)!|j}
      /*style=Style.(style [color "#000"])*/
    />
};
