In parse.y foo(**h, **{}) passes h through as if it were foo(**h)

def kw(**k) = k

p kw(**Hash.new(5), **{}).default                   # expected nil, got 5
p kw(**Hash.new { 7 }, **{})[:x]                    # expected nil, got 7
p kw(**{a: 1}.compare_by_identity, **{}).compare_by_identity? # expected false, got true
p kw(**Class.new(Hash).new, **{}).class == Hash     # expected true, got false
