When an :opt arg is specified with :rest and :key args,
Proc#parameters (as well as *Method) cannot show it as below:

->(opt = :ion, *rest, key: :word){}.parameters # => :rest, :rest], [:key, :key

I've started to take a look at this, and I wish to solve it if I find the way.
But of course if I'm taking too much time or somebody solves it before it's fine,
although I would prefer collaborating with them (I suppose mame, as he did r34137).
