I do not understand exactly the nature of the objections. It seems to me
to be a fairly innocuous notational shortcut. If I understand correctly the
proposal, it is just that when you have a method

     def f(a,@b,c)
     ...
     end

it is understood as exactly equivalent to

     def f(a,dummy,c)
     @b=dummy
     ...
     end

unless I missed something?

 What is ugly? That by analogy someday someone might ask

     def f(a,$b,c)
     ...
     end

to be a shortcut for

     def f(a,dummy,c)
     $b=dummy
     ...
     end

I must confess I don't see the problem here either. Please bring light.
