Yes, that would be useful. It has been discussed many-a-time, before, 
too. :) For now, you'll have to implement your own solution in-method:
def []= *args
  cords, value = args[0..-2],args[-1]
  #...
end

Personally, I'd also like to see this:

def []= x, y, value
  #...
ordef x, y, z, value
  #...
ordef *args   #gets here only if neither of the first two match
  #...
end

But none of this exists. So live with it. :)

(I'd say, "Go write an RCR," but I can't imagine that 3 don't exist 
already.)
