That's exactly what I was going to say.

The author says this about parameter skipping:

   Personally I’m not particular fond of this proposal. 
   In my eyes code that needs this feature is just badly
   designed. Functions shouldn’t have 12 optional parameters.

I'm not fond of this proposal either, for it doesn't solve a problem named parameters do, which is that sometimes function parameters don't have a logical order, and cramming them into an array feel sloppy as hell.
