Class literal properties

[rpominov]

class Id<T> {
  _x: T;
  constructor(x: T) {
    this._x = x
  }
  static 'fantasy-land/of'<T>(x: T): Id<T> {
    return new Id(x)
  }
}

Flow yields:

11:   static 'fantasy-land/of'<T>(x: T): Id<T> {
      ^ literal properties not yet supported

From error message I understand that Flow team aware about this issue, but I just wanted to give you another use-case (we need this for Fantasy Land) and open an issue to track progress if that's ok.

This should also be added to the list in #560 .

Sure you don't need the computed property square brackets? static ['fantasy-land/of'] () {}

@Kovensky I think it's valid ES with or without square brackets in this case. At least it works in babel and latest Chrome without them.

With brackets Flow complains as well:

11:   static ['fantasy-land/of']<T>(x: T): Id<T> {
      ^ computed property keys not supported

This is a known issue. We currently don’t support it, but we should be adding support in the future 👍
