Class: Set

Override #== to fix behavior where it seems to ignore overrides of Object#== or Object#eql? when comparing set elements. Note that we can‘t put these definitions inside a helper module, as we do for other methods, and include in the reopened Hash class. If we do this, the method is not used!

Alias for #==

intersection_using_eql_comparison(other)

It seems that Set#& should work, but for some reason, it doesn‘t.

25:     first = dup
26:     second = other.dup
27:     first.size > second.size ? do_intersection(first, second) : do_intersection(second, first)
28:   end

union_using_eql_comparison(other)

It seems that Set#| should work, but for some reason, it doesn‘t.
