Bug #10016

Updated by nobu (Nobuyoshi Nakada) over 5 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

[#<Object:0x007fc5fb212870>, [nil], 1, {:x=>9}]

$ ruby -v destructure_bug.rb

~~~


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

Is this a bug?
