Bug #12002

Updated by nobu (Nobuyoshi Nakada) over 8 years ago

I found the regression regarding the handling of the `**` ** notation for options hash in a method. In ruby 2.1 and lower, it seems to always be handled in the same way, i.e. it is always the same object: 

 ```ruby <pre> 
 def hashie1(o={}) 
   puts o.object_id 
 end 
 def hashie2(**o) 
   puts o.object_id 
 end 

 v={} 
 puts v.object_id 
 hashie1(v) 
 hashie2(v) 

 # 2.0.0 
 69830362391800 
 69830362391800 
 69830362391800 

 # 2.1.6  
 69884363736320 
 69884363736320 
 69884363736320 

 # 2.2.4 
 69922787909840 
 69922787909840 
 69922787909700 

 # 2.3.0 
 69915134419200 
 69915134419200 
 69915134419000 
 ``` </pre> 

 I didn't find any documentation regarding this change. Is it supposed to work the way it works in 2.2 and 2.3? Because my understanding was that `**` ** was supposed to be the new notation and should just work as the previous notation.
