SortedSet error: "reverse is not a function"

[axelpale]

I installed collections 5.0.6 via NPM today:

$ npm install --save collections

Then I tried to get a sorted set with the largest value first (smallest first by default) by calling reversed():

> var SortedSet = require('collections/sorted-set')
> var ss = new SortedSet([2, 8, 5, 3, 11])
> ss.toArray()
[ 2, 3, 5, 8, 11 ]
> var iss = ss.reversed()
TypeError: this.constructClone(...).reverse is not a function

The docs claim SortedSet to have a reversed() method:
http://www.collectionsjs.com/sorted-set
http://www.collectionsjs.com/method/reversed

The docs also claim that reverse() (without d) method is only available for List:
http://www.collectionsjs.com/method/reverse

What I was expecting was that reversed() would return another SortedSet with same contents but inverted sorting order.

I also have this issue. Can this be fixed?

See also #223. I probably should have looked at this first. This has been open since 2017?
