Subject: [ruby-talk:17729] Array#sort! returns nil when array empty

Hello,

Array#sort! returns nil if the array is empty, whereas ri says it should
return itself:
     arr.sort! -> arr 


irb(main):007:0> [3,1,2].sort!
[1, 2, 3]
irb(main):008:0> [].sort!
nil
irb(main):009:0> [3,1,2].sort 
[1, 2, 3]
irb(main):010:0> [].sort 
[]
