Return with Splat in Ruby 1.9

This looks like a bug to me…(‘cept I’m sure it’s not)

$ cat splats.rb 
def splat1
  rv = [nil]
  return *rv
end

def splat2
  rv = [nil,nil]
  return *rv
end

foo = splat1
bar, baz = splat2

puts foo.inspect
puts bar.inspect
puts baz.inspect

$ ruby -v
ruby 1.8.7 (2009-04-08 patchlevel 160) [i686-darwin9.6.0]
$ ruby splats.rb 
nil
nil
nil

$ ruby -v
ruby 1.9.1p129 (2009-05-12 revision 23412) [i386-darwin9.7.0]
$ ruby splats.rb 
[nil]
nil
nil

(Notice the difference when returning the splatted array [nil].)

EDIT: I forgot to check the ‘question’ box on Tumblr, but if you know what’s going on here, please get it touch.
