Description

Using ruby 2.2.2 I see this work:

[18] pry(main)> def test(cmd, opts={})
[18] pry(main)*   puts cmd,opts
[18] pry(main)* end  
=> :test
[19] pry(main)> test(:ads, :d => 6, :f => :gah, {a:3,b:4} => 3)
ads
{:d=>6, :f=>:gah, {:a=>3, :b=>4}=>3}
=> nil

But this fails:

[2] pry(main)> def test(cmd, **opts)
[2] pry(main)*   puts cmd, opts
[2] pry(main)* end  
[9] pry(main)> test(:ads, :d => 6, :f => :gah, {a:3,b:4} => 3)
ArgumentError: wrong number of arguments (2 for 1)
from (pry):2:in `test'
