Bug #10016

Updated by nobu (Nobuyoshi Nakada) over 10 years ago

The following code: 

 ~~~ruby 
 # destructure_bug.rb 
 def m 
   x = Object.new 
   def x.to_hash() {x: 9} end 

   yield [1, 2, 3, x] 
 end 

 p m { |a, *b, c, **k| [a, b, c, k] } 
 ~~~ 
 

 gives: 

 ~~~ 
 $ ruby -v destructure_bug.rb 
 ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin13.0] 
 [#<Object:0x007fc5fb212870>, [nil], 1, {:x=>9}] 

 $ ruby -v destructure_bug.rb 
 ruby 2.2.0dev (2014-06-05 trunk 46353) [x86_64-darwin13] 
 [#<Object:0x007f88c206c2a8>, [nil], 1, {:x=>9}] 
 ~~~ 

 I would expect: `[1, [1, [2], 3, {:x=>9}]` {:x=>9}] 

 Is this a bug?
