Bug #8993

Updated by nobu (Nobuyoshi Nakada) over 10 years ago

=begin 
 I recently fixed keyword arguments in the JRuby interpreter, and I then found an example for which MRI and JRuby have different behavior: 

   def foo(a, b, c=1, *d, e, f:2, **g) 
     [a, b, c, d, e, f, g] 
   end 

   foo(1, 2, f:5) 

 MRI raises:  
   ArgumentError: wrong number of arguments (2 for 3+) 

 ... whereas JRuby produces: 

   [1, 2, 1, [], {:f=>5}, 2, {}] 

 I implemented the behavior in JRuby to conform with MRI, but in this case, I think that JRuby's behavior is correct, based upon the discussion in #8040. 

 Is there a spec for this feature somewhere (aside from the RSpec specs that I submitted to the RubySpec project)? In #7529, Matz refers to "the spec" for this feature, but I don't know where or what that is.
