Warning: Invalid argument supplied to oneOf, expected an instance of array.

There seems to be no true IPT equivalent of oneOf, which is problematic if you want to check that a prop is an exact match for an immutable map that exists in a constant immutable list.

const COUNTRIES = [
  {...},
  {...},
  {...},
  {...},
  {...},
  {...},
];

const IMMUTABLE_COUNTRIES = Immutable.fromJS(
  COUNTRIES
);

var countryShapeImmutable = React.PropTypes.oneOf(
  IMMUTABLE_COUNTRIES // fails
);

ExceptionsManager.js:71Warning: Invalid argument supplied to oneOf, expected an instance of array.

Is there a way to check for a specific immutable country here, using immutable proptypes?

Has anybody found a solution/workaround for this?
