Bug #17179
Updated by sawa (Tsuyoshi Sawada) about 4 years ago
```ruby
some_instance = Class.new { def some_setter=(a:, b:); end }.new
setter_params = { a: 1, b: 2 }
some_instance.some_setter = setter_params # => {:a=>1, :b=>2}
# warning: Using the last argument as keyword parameters is deprecated; maybe ** should be added to the call
# warning: The called method `some_setter=' is defined here
some_instance.public_send(:some_setter=, **setter_params) # => nil
# No warninigs, everything is ok
```
If this behavior is okay, probably we need to add the ability to use the double splat operator with syntax sugar like in example below:
```ruby
some_instance.some_setter = **setter_params
```
