2.4.0.rc4 'ArgumentError: unknown keywords' when using keywords args w/unified lambda args

[davidcpell]

Loving 2.4 so far! Today I ran into an issue with the keyword args option for lambdas:

Using this per the blog example:

  property :team_id, 
    as: :teamId, 
    setter: ->(fragment:, doc:) { puts "#{fragment}" }

...raises the following exception:

ArgumentError:         ArgumentError: unknown keywords: options, represented, decorator, binding, input, as, user_options

If I add more keyword args (e.g. decorator:), that arg disappears from the error list. Likewise if I take keyword args away, they appear in the error list. It seems as if I'm being expected to either pass a singular variable 'options' or every single keyword possible variable.

Using options:

  property :team_id, 
    as: :teamId, 
    setter: ->(options) { puts options[:doc] }

...works without raising any exceptions.

So far I've had to resort to the old positional args to get the desired behavior:

  property :team, 
    as: :teamId, 
    setter: ->(val, *) do 
      self.team = team_model.stats_find(val)
    end

You simply have to use the hash splat for keyword arguments.

->(fragment:, **)

I will update the blog post, thanks!
