Subject: Re: method overloading?

Yes, this would solve the problem but it's not ideal or elegant, the 
code is now much less obvious.

For example:

class Bank
   def open(safe, combination)
   ...
   end

   def open(window)
   ...
   end
end

is a lot more revealing than:

class Bank
   def open(*args)
     if args.length == 1
      ...
     elsif args.length == 2
      ...
     end
   end
end

Thanks for the help though, it just feels like overloading could be 
done in a simpler manner.
