Passing a hash without required key (:keyreq) to a method which takes 
keyreq: and **keyrest,
then a same hash is set to both keyreq and keyrest.

 def m(keyreq:, **keyrest)
   [keyreq, keyrest]
 end

 m(keyreq: 1, keyrest: 2) # => [1, {:keyrest => 2}] OK
 m(unknown: 3) # => [{:unknown=>3}, {:unknown=>3}]  ??
