Subject: Re: not grasping the method overloading/multi-dispatch thing

I just got a better idea for RHDL:
 class Signal
   def call
       proc{self.to_s}.call
   end
   #....
   def assign_at (relTime=0,nextValue=Proc.new)
     nextValue = nextValue.call if nextValue.respond_to? :call

     @eventQueue[relTime] = nextValue
     nextValInQueue = @eventQueue.shift
     @next_value = nextValInQueue if nextValInQueue
   end
 
   def assign(nextValue=Proc.new)
       assign_at(0,nextValue)
   end
   #....
 end
 
2 changes:
* made the common function call, so you don't have to change Proc
* made function.call a guard, so that you don't have to change Object

This is kind of cheating, since I'm checking some type.  But this is
why I like Ruby giving a way to do so, even if I don't prefer it :-)
