There Is No Goto.  ;)

call: aComponent
      ^ self delegateTo: aComponent during: [aComponent call]

delegateTo: aController during: aBlock
	    |value saved|
	    saved _ self delegate.
	    self delegate: aController.
	    value _ aBlock value.
	    self delegate: saved.
	    ^ value

delegate: aController
	  delegate ifNil: [delegate _ WAStateHolder new].
	  delegate contents: aController	  
      
I got a little confused there.

I don't really mind either.  It's easier to express "purpose" using
#call: and #goto: but besides that..
