Already there. 

I use Continuation Passing Style, e.g. to animate card moves. 

Feature require: 'Morphic-Games-Solitaire'. 

===== 

CardTableMorph>>
slide: aMorph to: endPoint nSteps: numSteps delay: milliSecondsDelay
next: nextAction
"Slide from current to new position -- in owner's coordinates"
"Nota Bene: Asynchronous. When complete, nextAction value" 

| startPoint delta stepCount |
startPoint _ aMorph morphPosition.
delta _ (endPoint - startPoint) / numSteps.
stepCount := 0.
aMorph when: #morphicStep 
evaluate: [ :ignoredArgument |
stepCount := stepCount + 1.
(stepCount < numSteps)
ifTrue: [ 
aMorph morphPosition: (startPoint + (stepCount * delta)) rounded; 
redrawNeeded 
]
ifFalse: [ "done"
aMorph stopStepping.
aMorph morphPosition: endPoint.
aMorph removeActionsForEvent: #morphicStep.
nextAction value
]
].
aMorph startSteppingStepTime: milliSecondsDelay!
