Can use a dot instead of a comma

[jsiebern]

I just came across this while writing some bindings:

module ModalContent = {
  @react.component @bs.module("semantic-ui-react")
  external make: (
    ~style: ReactDOMRe.Style.t=?.
    ~image: bool=?,
  ) => React.element = "ModalContent";
}

Look at the end of the style argument. The compiler accepts the . instead of the , seemingly just fine. You can also write it in one line without spaces, still doesn't complain.

@jsiebern Thanks for the report! This parser is too powerful, will make it a bit more strict
