Description updated

----------------------------------------
Bug #12970: == Equality of recursive sets fails
https://bugs.ruby-lang.org/issues/12970#change-61641

* Author: Kevin de Berk
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: 2.2.5, 2.3.3
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
Comparing recursive arrays and hashes with equal? contents (save for the recursive element) using == succeeds.
However, using == to compare two recursive sets with equal? contents fails. I expect that to succeed.

See the attached script. This is my output for 2.2.5 and 2.3.3:

~~~
[1, 2, 3] == [1, 2, 3]? -> true
[1, 2, 3, [...]] == [1, 2, 3, [...]]? -> true
{:a=>1, :b=>2} == {:a=>1, :b=>2}? -> true
{:a=>1, :b=>2, :c=>{...}} == {:a=>1, :b=>2, :c=>{...}}? -> true
#<Set:0x00000001f90fc8> == #<Set:0x00000001f90500>? -> true
#<Set:0x00000001f92968> == #<Set:0x00000001f91478>? -> false
~~~
