That's the safe play for ES6, which must be prototyped and drafted this 
year, pretty much limiting new complexity.

As noted in the other thread, we're now talking about a pattern language 
for matching (refutably or irrefutably), which was proposed last year:

Happy to use es-discuss to work out something richer than ES6 
rest-only-at-end. I write this not to nag anyone, just to make my own 
position clear in case it sounded like I was against the idea of richer 
patterns than rest and destructuring as currently proposed or drafted. 
I'm not! Let's discuss.
