Bug #10016
closedDestructuring block arguments with a Hashable last element
Description
The following code:
# 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, [2], 3, {:x=>9}]
Is this a bug?
