def f(opts)
   a, b, c = nil
   Quix::Vars.hash_to_locals opts, binding
   p b
end

Now I know I'm handing the keys to my local scope to some other call, 
and the world isn't as scary!

Quix::Vars.locals_to_ivs %{x, y, z}, binding

Better! :)

If it's the extra size of the binding call that people object to, I 
wouldn't be opposed to another magic variable that does the same 
thing...is $- taken?

If it's the extra parameter...I agree partly, but I feel better with it 
explicit.
