I'm not sure if we _can_.  yacc is a tough guy to fight with.

In this article, you've proposed *rest to slurp keyword hash.  Indeed
it is simple, but maybe too simpler.  I don't get how it can co-exist
with _your_ ideal keyword parameters.  I.e. how the following code
should work?

 def foo(a, b=0, *c)
    ...
 end

 foo(1, foo:3)     # (a=1, b={:foo=>3}) or (a=1,b=0,c=[{:foo=>3}])?
 foo(1, 2, 8, c:5) # c={:c=>5}) or c=[8,{:c=>5}] or error?
 args = [1, {:b=>2, foo=>5}]
 foo(*args)        # (a=1,b={:b=>2, foo=>5}) or (a=1,b=2,c=[{:foo=>5}])?
