[ruby-core:58206] [CommonRuby - Feature #8626] Add a Set coercion method to the standard lib: Set(possible_set)

From: "saturnflyer (Jim Gay)" <jim@...>

List: ruby-core #58206
Issue #8626 has been updated by saturnflyer (Jim Gay).


This has been merged into ruby trunk in https://github.com/ruby/ruby/commit/ad78cf4ea8613c7e1790c5e3a2718a35fe32115f
----------------------------------------
Feature #8626: Add a Set coercion method to the standard lib: Set(possible_set)
https://bugs.ruby-lang.org/issues/8626#change-42787

=begin
I'd like to be able to take an object that may already be a Set (or not) and ensure that it is one

For example:

    set1 = Set.new
    set2 = Set(set1)
    set3 = Set(nil)
    assert set1.equal?(set2)
    assert_instance_of(Set, set3)

This is different from the behavior of Set.new in that it will return the same set rather than creating a new one

    set1 = Set.new
    set2 = Set.new(set1) # <--- completely new object in memory
    set2 = Set(set1) # <--- same object from memory

My thoughts about the implementation are simple:

    def Set(possible_set)
      possible_set.is_a?(Set) ? possible_set : Set.new(possible_set)
    end

I'm not sure if there are edge cases to unexpected behavior that I haven't thought of and I'm wondering if it ought to have a Set.try_convert as well
=end
