Description

The just released BS 7.0.2-dev.1 with the latest refmt compiles

type request;

[@bs.obj] external request: (~method: string) => request = "";

Js.log2("request", request(~method="GET"));

to

console.log("request", {
      method_: "GET"
    });

I.e. it gives me an object with a field method_. In previous versions, I used to get an object with a field method (as expected).

Research direction

Reproduce the Reason snippet with BS 7.0.2-dev.1 and the latest refmt, then compare its generated JavaScript with the previous version. Trace the refmt handling of the external argument named method; done when the generated object uses method rather than method_.
