Does the check for unknown positional parameters work?

Hi,

thank you for this useful gem! I have one question about the design choice of how to generate the constructor of the object.

https://github.com/dry-rb/dry-initializer/blob/3167b5aee1d093886fe02448901db5a851f74d7b/lib/dry/initializer/builders/signature.rb#L8-L10

Why is the '*' included in the parameter list? Wouldn't that just match all positional arguments regardless of whether they are defined or not?
