Backport #4196: Array#flatten!(0) should return nil

• Status: Closed

=begin
Since Array#flatten!(0) does not modify the array I believe it should return nil. At the moment, in 1.8.7-p302, it returns itself.

irb(main):001:0> [1,[2,3,[4,5]]].flatten!(0)
=> [1, [2, 3, [4, 5]]]

Note that JRuby 1.5.6 returns nil for the above code, so either MRI is wrong or JRuby is wrong.

To wit, 1.9 returns nil as well.

$ irb1.9
irb(main):001:0> RUBY_DESCRIPTION
=> "ruby 1.9.3dev (2010-12-18 trunk 30244) [x86_64-darwin10.5.0]"
irb(main):002:0> [1,[2,3,[4,5]]].flatten!(0)
=> nil

=end
